Looks like you missed something in the question ..

But, yes to answer the question, if a^-1 is undefined, that means a = 0, so that should be sufficient to answer the original question.

Nope nothing is missing.. OA is A.. As it explains that 1/0 is undefined. I thought 1/0 was defined as infinity.. :)

should be A.

1. a^-1 = 1/a. if 1/a is undefined, a should be 0. so suff.
2. b = 2 is not suff..
