The most appropriate variables for the code segment are those suggested in Option C.
Explicación
## Step 1The problem is about choosing the most appropriate variables for a code segment that represents a student's name and whether or not the student is currently absent. The variables should be chosen based on their relevance to the information they are meant to represent.## Step 2Option A suggests using a string variable named '' and a Boolean variable named 'a'. While the Boolean variable is appropriate for representing the student's absence, the string variable '' is not specific enough. It could represent any string, not necessarily a student's name.## Step 3Option B suggests using a string variable named '' and a numeric variable named 'n'. The numeric variable 'n' is not suitable for representing the student's absence, as it is not a Boolean value. It could represent any number, not necessarily the number of absences.## Step 4Option C suggests using a string variable named 'tudentName' and a Boolean variable named 'isAbsent'. The string variable 'tudentName' is specific and appropriate for representing the student's name. The Boolean variable 'isAbsent' is also appropriate for representing the student's absence.## Step 5Option D suggests using a string variable named 'tudentName' and a numeric variable named 'numAbsences'. The numeric variable 'numAbsences' is not suitable for representing the student's absence, as it is not a Boolean value. It could represent any number, not necessarily the number of absences.
