What does "debugging" involve in software development?

Debugging in software development specifically refers to the process of identifying, isolating, and removing bugs or errors from a program. Bugs can manifest in various forms, such as syntax errors, logical errors, or runtime errors, and can cause the program to behave unexpectedly. Debugging involves a systematic approach to locate these issues, which may include using debugging tools, reading error messages, stepping through code, and analyzing program behavior to ensure the software performs as intended.

This option is correct because it captures the essence of debugging: the direct actions taken to fix code that is not functioning correctly. Engaging in debugging is crucial to ensure software quality and performance, making it an integral part of software development.
