Final answer:
The type of activity normally used to find and fix a defect in the code is debugging. Debugging involves identifying and resolving errors or bugs in a computer program.
Step-by-step explanation:
The type of activity normally used to find and fix a defect in the code is debugging. Debugging is the process of identifying and resolving errors or bugs in a computer program. It involves using tools and techniques to trace the execution of the program and diagnose the root cause of the problem.
During debugging, developers often use dynamic analysis to examine the behavior of the program while it is running. This includes stepping through the code line by line, setting breakpoints, and inspecting variable values to understand how the program is executing and identify any issues.
While static analysis can also be helpful in finding defects in the code by analyzing it without executing it, it is not the most common activity used for directly identifying and fixing defects, unlike debugging.
