In the absence of complete question it is difficult to take the approach.
Asuuming, it is a DS question, the expression will be sqrt[(2x + y)^2].
In order to get the value of expression, both x and y are required. Hence, C.

Is it a data sufficiency question?  Please specify. As scthakur posted before, if DS type question then answer is (c).

(2x+y)^2 = 43 Edit:(2x+y) = 43 Forgot to remove the square.
