would go with D

I may not explain it very well but here is what I think:
a,b c do not have a verb to complete the clause that began with El Nino, however d & e have IS that is completing the clause. The 'IN WHICH' in d is better than 'where' in E. also E sounds odd otherwise.

D

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
--> El Nino,..., a phenomenon in which changes in.. allow water that has accumulated in the western Pacific to flow back to the east.
This is not a complete sentence at all

(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating
--> same as in (A)

(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated
--> same as in (A)

(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
-->correct

(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating
--> too wordy, "allow the warm water accumulating" is not correct grammar.

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated
(B) 'are combining' is inapporpriate
(C) meaning of sentence changed
(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated
(E) 'are combining' is awkward

Between A and D, I'll take D. 'is a phenomenon' would point to El Nino instead of the periodic abnormal warming.

I have chosen D for this question:

A. Sentence is a fragment because it lacks a main verb. Currently, the sentence has 2 modifiers for El Nino - the 2nd modifier is therefore misplaced at the moment.

B. Sentence is a fragment because it lacks a main verb.

C. Again, the sentence is a fragment.

D. This sentence is correct. The use of present perfect tense is fine because it is describing how water accumulated in the past and continues to accumulate in the present will flow back East.

E. The use of "where" to describe phenomenon is incorrect because "where" is used to describe places, not events. Also, "are combining" is really confusing. If this is correct, then we a have a parallelism error because "are combining" is not parallel to "allow."

Agree with the explanation . Will go with D

C has an incorrect structure: if you eliminate the modifer " the periodic abnormal warming of the sea surface off Peru" you'll see that the word "is" must be present

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

C looks like this: El Nino a phenomenon in which . There is something missing... like a verb...

Hope it's clear

hi Guys,

it has to be "D"

1)the sentence cannot stand without the verb "is" here.
thus A B C are eliminated

2)a phenomenon where is wrong...=> on GMAT where can only be used to refer place & its relation. Thus E gets knocked off.

Cheerz!!
