I

If we didn't write center of enlargement as B and just write Origin (0.0).. it is the same right ?

No. The origin means that a point O (from which position vectors lead). Center of enlargement was B. I wrote origin. It's INCORRECT.

Man B itself was origin..
I can prove that..

No, you can't. In vectors, the origin is O (0,0). Not B. If B was the origin it would have coordinates (0,0). The fact is, they WANTED us to derive this from ABCD and PBQR, which many of us didn't which means we'll lose the one mark.
