Consider statement 1. A+B>6, infinitely many solutions for A and B. INSUFFICIENT
Consider statement 2. A*B<7, can be 3*2 or 6*1 or 5*1 etc. INSUFFICIENT.
Consider together, only criteria where the conditions fit are A+B=7 and A*B=6 i.e. A=6 or 1 and B=6 or 1. INSUFFICIENT
Ans is E

Consider together
Remember A and B are non-negative integers
So they can take value zero as well
So cases are
(1,6) or (6,1) or (0,7) or (7,0)
Ans is E
