List K consists of 12 consecutive integers. If -4 is the least integer in list k, what is the range of positive integers in list k?

1. 5
2. 6
3. 7
4. 8
5. 9

OA is B. Can someone please explain (I got OA C )

Very simple..
the problem is asking the range of POSITIVE integers.
So the list K contains numbers from
-4.... 0, 1,... 7.

So the range of Positive integers = Largest +ve int - least +ve int.
ie 7 -1 = 6.

I think u assumed 0 to be Positive.
Takeaway:
1. 0 is neither Positive nor Negative.
2. read the Q carefully.
