To clarify the intent of the problem, I've added the phrase in red:

a. 251
b .252
c .502
d. 750
e. 884
Let a and b be the two integers greater than 250.
Since there is no requirement that a and b be distinct, let a=251 and b=251.
In this case, the smallest value divisible by both a and b -- in other words, the LEAST COMMON MULTIPLE of a and b -- is 251.
Eliminate B, C, D and E, which are all greater than 251.

The correct answer is A.

Mitch, what if we were asked to select two distinct numbers greater than 250?

I believe in that case the result would be 502 because the possible numbers are:

A = 251
B = 251 x 2
R A H U L

I think the assumption that the 2 nos. could be the same makes this a high difficulty level question.
Thanks,

Although this could be a pretty tricky question, we see that we are not told that the integers must be unique, and thus they could be equal to each other. So the smallest common multiple of two integers that are both greater than 250 is 251, since both integers could be 251.

Answer: A
