Which of the following is correct with regards to debugging?
A . Debugging identifies the cause of a failure
B . Debugging is often performed by test engineers
C . Debugging is considered part of the testing activities
D . Debugging is intended to find as many defects as possible in the code

Answer: A

Explanation:

Debugging is the process of finding, analyzing and removing the causes of failures in software. Debugging is not considered part of testing, but rather a development activity that can involve testing. Debugging is not intended to find as many defects as possible, but rather to fix the specific failure that was observed. Debugging is usually performed by developers, not by test engineers.
