The answer is A.

A=B=1 can be deduced from (A*B)! is odd. but not from A*B is odd

I go with C

From (1) , A = 0 and B = 0
OR A = 1 and B = 0
OR A = 0 and B = 1
OR A = 1 and B = 1 , thus insufficient

From (2) A = 1 and B =1 is one of the many possible solutions

To satisfy both (1) and (2) , A = 1 and B = 1 are the only possible values

Since there is no stipulation on whether A or B are integers, then A=0.25 and B=4 (or vice versa) can satisfy both conditions. The answer would have to be E.

I think you are right, since 0!=1
