• A. Testing
• B. Profiling
• C. Debugging
• D. Refactoring

Answer: (C)

Debugging is the process of locating and removing bugs in a program. When something behaves unexpectedly, debugging starts by reproducing the issue, tracing the execution path, and inspecting variables and state to find where things go wrong. Developers use debugging tools, add logging, or step through code to identify the exact spot that causes the defect, then fix that code and verify the fix by running tests again to confirm the problem is resolved and no new issues were created.

Testing is the broader activity of trying to uncover defects by executing the program and checking its behavior, while profiling focuses on measuring performance characteristics rather than fixing correctness, and refactoring is about restructuring code to improve readability or maintainability without changing what the program does.
