El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating


Can someone explain the solution for this question? Also why is option A wrong??

I'd be happy to answer your questions, but could you please re-post them in separate threads? The convention is one OG problem per thread, so that people can more easily search and follow discussions.

In A, B and C, El Nino (subject) lacks a verb.
Eliminate A, B and C.

where must serve to refer to a PHYSICAL PLACE.
In E, where incorrectly serves to refer to a phenomenon, which is not a physical place.
Eliminate E.

The correct answer is D.
