I think you're right, nithi. What about this though - if they said that Set S contained n "unique" positive integers, would that make the answer C?

You need a difference of 5, so you could have: 8, 7, and 3. Or 9, 4, and 5. So I guess that doesn't work either (55 in the first and 56 in the second).

I thought I could find a way to make it C, but I guess it's definitely E, even if they give a little extra information.
