Why must a program be tested again after finding and fixing an error?
A. to enable the beta testers to see the fix
B. to ensure that fixing the error did not cause another error
C. to run the program line by line
D. to check for extra comments in the code that may be left after debugging

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.
