Answer:
Option B
Explanation:
The answer is option B " to ensure that fixing the error did not cause another error." Always check your program after you fix a issue to make sure you didn't start another issue or to find out if what you fixed in the program is being caused by something else. Doing so would reduce time and other issues in your program.
Hope this helps.
B, because the code could be messed up from when you changed one thing.
