1. Mark for Review Three different numbers need to be placed in order from least to greatest. For example, if the numbers are ordered 9,16,4, they should be reordered as 4,9,16 Which of the following algorithms can be used to place any three numbers in the correct order? A If the first number is greater than the last number, swap them. Then if the first number is greater than the middle number, swap them. B ) If the first number is greater than the middle number, swap them Then, if the middle number is greater than the last number, swap them. C If the first number is greater than the middle number, swap them. Then if the middle number is greater than the last number, swap them. Then, if the first number is greater than the last number.swap them. D If the first number is greater than the middle number, swap them.Then, if the middle number is greater than the last number, swap them. Then, if the first number is greater than the middle number,swap them.

The correct answer is 'C'.
Explicación
## Step 1The problem is asking us to identify the correct algorithm that can be used to arrange any three numbers in ascending order. The algorithm should involve swapping the numbers based on their relative positions.## Step 2Let's analyze each option:### Option A:This option suggests swapping the first and last numbers if the first number is greater than the last number. Then, it suggests swapping the first and middle numbers if the first number is greater than the middle number. However, this algorithm does not guarantee that the numbers will be in ascending order.### Option B:This option suggests swapping the first and middle numbers if the first number is greater than the middle number. Then, it suggests swapping the middle and last numbers if the middle number is greater than the last number. This algorithm does not guarantee that the numbers will be in ascending order.### Option C:This option suggests swapping the first and middle numbers if the first number is greater than the middle number. Then, it suggests swapping the middle and last numbers if the middle number is greater than the last number. Finally, it suggests swapping the first and last numbers if the first number is greater than the last number. This algorithm guarantees that the numbers will be in ascending order.### Option D:This option suggests swapping the first and middle numbers if the first number is greater than the middle number. Then, it suggests swapping the middle and last numbers if the middle number is greater than the last number. Finally, it suggests swapping the first and middle numbers if the first number is greater than the middle number. This algorithm does not guarantee that the numbers will be in ascending order.
