A) says one or both of the integers could be -ve. Not suff

B) likewise

C) One positive, one negative, and consecutive indicates the two are 1,-1.

Would be C

What if the series is -3 -1 1

series of odd numbers but sum is -3
So we have a number of combinations possible so answer shud be E

The question is asking only for a pair of consective odd integers. 3 numbers cannot be used.

Hope this helps!!
