Correct me if I am wrong but
c) 4x + y
.

I am sure C is - 3x + y
D is 3x + y + z

Do not know where 4x came from?

Because ED = x and AE = 3ED = 3x so AD = 4x. Can you see?

You just add z for D.

It wouldnt be -3x as the arrow is pointing in the right direction (AC).

It is also 4x, instead of 3x, because 3x only represents AE, whereas to get to AC, you need to do: AD + DC ...which is the same as: 4x + y

Hope this helps (:
