(1) 0*2=2 --> operation * represents addition --> 1*0=1+0=1. Sufficient.

(2) 2*0=2 --> operation * represents either addition or subtraction --> 1*0=1+0=1 and 1*0=1-0=1, the same answer. Sufficient.

OA must be wrong.

I think it's D but that's not OA.

It is a tricky question. In B. + or - is does not change the answer of the question
