The sums of integers can be either positive or negative.

A
two positive

B
two negative

C
positive and negative

D
three positive

The answer would be C.

Step-by-step explanation:

The sum of positive and negative intergers can be either positive or negative.

This is true because, for example:

-6 +3 = -3 while,

6 - 3 = 3

While these numbers are able to be both negative and a positive, you can get a positive and a negative answer from both.

A and D would not be correct, because if you have only two positive numbers or more, you can only get a positive number, for example:

2 + 2 = 4 and

3 + 3 + 3 = 9

B would have been correct if they wanted the product of integers, because the only times when you can get a positive from negatives numbers is when you multiply or possibly divide.

Hope this helps!
