A class III student solves al subtraction problem as

As a mathematics teacher how will you support the student to rectify the error in most appropriate manner?

Correct option is D

To support the student in rectifying the error in the most appropriate manner, you can choose: Ask the student to count backward after representing 101 and 93 on a number line before teaching the formal algorithm.
This approach encourages the student to develop a conceptual understanding of subtraction by visualizing the process on a number line, promoting a deeper understanding before moving to the formal algorithm. It provides a concrete and visual representation of the subtraction process.
