Here  only option  (4) i.e   296 + 1  is greater than  (232+1)  so this will be the answer.

Alternately;

Let 232 = a   and  b =1

Use the formula : a2 - 1 = (a + 1)(a - 1)

for a  = 232 ;    (264 - 1) =  (232+1) (232-1)  so  (264 - 1) will be divisible by (232 + 1)  but it is not in the option.

Use formula :  (a3 + 1) = (a + 1)(a2 - a + 1)

So,  (296+1)  = (232+1)(264 - 232+1)   so (296+1) will be divisible by (232+1)
