Answer 2

C. ++ ++ ++ ++

Explanation:

Note that the numbers are positive 4 & positive 2 (which explains the + signs).

The answer can be two ways. 4 groups of 2, or 2 groups of 4.

C. ++ ++ ++ ++ is your answer, for it is 4 groups of 2. Note that A is not the answer, for that would be for adding, in which you have one group of 4 and one group of 2.
