B is the answer... x(a-c) + y(c-a) = x(a-c) -y(a-c) when you expand +y(c-a) which is from the actual question, you'll get the same result when you expand -y(a-c)... so in that case i can use -y(a-c) which will give x(a-c) -y(a-c) since the variables in the bracket are the same according to factorising law it'll give (x-y)(a-c)

I think d answer is obvious, its E. Is it not just to put them into bracket??
