I feel like there might be a catch here, but I can't recall any specific rules that would cause a compilation error.

I practiced a similar question where a macro was used, and it printed the defined value. So, I lean towards option B.

I'm not entirely sure, but I remember something about macros in C++. Could it be a compilation error?

I think it should print 0 since DEF_A is defined as 0.
