A class III student solves a subtraction problem as

\begin{matrix} 101 \\ −93 \\ 092 \\ \end{matrix}

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

Ask the student to see the answer of other students and correct the mistake.
Solve the problem on the blackboard and direct the student to observe the algorithm used carefully.
Give at least 10 similar types of problems to practice.
Ask the student to count backwards after representing 101 and 93 on a number line before teaching formal algorithm.
