We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it - 7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with - 7x.
