The second one has three dots after the numbers. This implies that the set is infinite.
Because the stated set isn't infinite, then the second one doesn't represent it.

nory · Answer

{5, 6, 7, 8... } by tradition means "all the positive integers greater than 5." But that's not what we want.
Does that answer your question?

so its D ? @Nory

nory · Answer

It would be B, I think. The second one.

anonymous · Answer

you said it isn't b in the first comment @Nory

nory · Answer

I meant that B doesn't represent the set. That is, it's the answer.
Sorry

So yeah, it's B. @shahbaaz786
