A) I only

C) I and II only
D) I and III only
E) I, II and III only

Can be rewritten as $$px-qx$$=0
$$x(p-q)$$=0
either $$x=0$$ or $$p=q$$, but it is given that p$$\neq$$ q hence $$x=0$$
Once $$x=0$$ then $$p$$ and $$q$$ can take any values as long as they are not equal , hence Q=0 is possible and $$p=q$$ is not possible. Thus only I and II are possible.

Ans - C
