Hmm, I'm leaning towards B. Something seems off with the structure declaration. Maybe it's missing a semicolon or something. I'll have to double-check the syntax.

Oh wow, this looks like a tricky one! I'm going to guess C, it prints 'Steve 31'. That pointer stuff is always a bit confusing, but I think the set function is modifying the age field directly.
