Shondra is almost finished writing her algorithm. She is trying to change her algorithm so that it works for a more complex problem. Which of the following steps in the algorithm process is Shondra most likely working on?

A. Making a plan
B. Carrying out the plan
C. Extending the problem
D. Understanding the problem

C. Extending the problem

C. Extending the problem

Based on the information provided, Shondra is almost finished writing her algorithm and is now trying to change it to work for a more complex problem. Since she has already completed the initial steps of understanding the problem and making a plan, it can be inferred that Shondra is most likely working on "extending the problem." This step involves modifying or expanding the existing algorithm to address the requirements of a more sophisticated problem.
