the question seems a bit ambiguous but A seems most likely ans.

(5$6)$2=5$(6$2) can be true when $ = * or +

1. $ can be + or *
2. $ is + or -

I agree with life is a test.

The answer is A

1st Stmt $ is addition or multiplication and when we plug both of them we got the same answer.
2nd Stmt $ is addition or subtraction and each of them has different answer.
