A) debug
B) design
C) expand

Debugging a macro means finding and fixing errors or issues in the code. This process helps to ensure that the macro runs correctly and achieves its intended outcome. Designing a macro involves creating the code and logic necessary to perform a specific task, while expanding and grouping refer to other actions that may apply to macros but are not directly related to identifying and resolving errors.
