what is the OE as here in this ques. i find no such issue with "human and artificial organs " but i would like to know what is wrong with A.. it is a bit weird but i don't seem any other reason to discard it..

7. A revolution has taken place in medical science as a result of the introduction of new methods of surgically implanting artificial and human organs.

(A) the introduction of new methods of surgically implanting artificial and human organs
(B) the introduction of new surgical implantation methods of human and artificial organs
can't find anything wrong with this, although i feel (a) gets the point across more efficiently.
(C) the surgical introduction of new artificial and human organ implantation methods
surgical modifies introduction
(D) the introduction of implantation methods of new artificial and human organs
here, it says the organs are new, not the method
(E) the introduction of methods of surgically implanting new artificial and human organs
see (d)

My answer: A

IMO: A

I wonder why B..
