D.
Some of the code could be moved to re-usable functions
Answers
D.
Some of the code could be moved to re-usable functions
Suggested answer: A

Explanation:

The pseudocode provided includes a while loop that adjusts the loop variable a within the loop's conditional code block. This adjustment, set a = 5, occurs when a > 10. Because the loop checks a < 12 as its continuation condition, and a is reset to 5 repeatedly once it exceeds 10, the loop will execute indefinitely, preventing termination. This creates an infinite loop situation since the condition a < 12 will perpetually remain true once a exceeds 10. This is a critical logic error needing correction for proper execution flow.
