# Explanation:## Step 1The problem is about the movement of Galaxy B in relation to the standard. The standard in this context is the observer's position.## Step 2The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 3The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 4The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 5The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 6The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 7The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 8The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 9The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 10The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 11The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 12The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 13The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 14The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 15The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 16The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 17The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 18The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.## Step 19The term "red-shifted" is used in astronomy to describe the phenomenon where the light from an object, such as a galaxy, is shifted towards the red end of the spectrum. This shift indicates that the object is moving away from the observer.
