Divisibility by 8:- The last three digit of a number is divisible by 8.

Divisibility by 9:- The sum of digits divisible by 9.

Given Number divisible by 8 if last 3 digits 96B is divisible by 8.There are two possibilities for B ( 8 and 0 ).

The number is divisible by 9 if the sum of digits (55+A+B) divisible by 9.

There are only 2 possibilities

A=0 and B=8

or

A=8 and B=0.

Hence,Option(B)8,0 is the correct choice.
