You need a set of _all_ positive intergers.
Look at each choice:
A is only 5 integers.
B is only 100 integers
C is all positive numbers, which means 1/3, sqrt(2), etc. (non-integers) are included
D is all integers starting with 1 and going on forever
Can you figure out which choice is the correct one?

so d ?

The question is " a set of integers" not a set of _all_ integers, so A, B and D are good.

i only need one .

Then again the question asks "Which of the following represents..." with "represents" being singular, so if it wants a single choice, I'd go with D.
