It is being given that (232 + 1) is completely divisible by a whole number. Which of the following numbers is completely divisible by this number?
Answer: Option
Explanation:
Let 232 = x. Then, (232 + 1) = (x + 1).
Let (x + 1) be completely divisible by the natural number N. Then,
(296 + 1) = [(232)3 + 1] = (x3 + 1) = (x + 1)(x2 - x + 1), which is completely divisible by N, since (x + 1) is divisible by N.

It is written in question no should be completely divisible.
For that number should be greater than given number i.e. 2^32+1.
Ex 1/2 = 0.5 (not completely divisible).
4/2 = 2 (completely divisible).
So option A, B, C all three numbers are less than given number 2^32 +1.
Now come on option D = 2^96+1. Clearly shows number is greater than 2^32+1.
This is what up to which some logic can b made.
Rest how it is possible to refer to given explanation of the question.
Thanks.
