IMO E.
IN THE GIVEN SENTENCE THE PART " such as those that occurred over the 20th century"==>this is a modifier.hence we can remove this.
sentence becomes:
Glaciers that are seated in deep submarine basins are vulnerable to small changes in ocean temperature have been rapidly retreating [/u]in the last decades.==> the error in this sentence is that two verbs are there and one subject
subject: glaciers....verbs: are vulnerable...and have been......=>whenever two verbs are there and both verbs belongs to same single subject then we have to connect those two verbs using a conjunction depending on the meaning of sentence.
more over in the last part of non underlined section we have: IN THE LAST DECADE===> THIS is a marker for present perfect tense...so use of HAVE (AS THE SUBJECT IS PLURAL).
NOW basing this two error (conjunction is required and use of have is required)we can eliminate A,B,AND C.
now left with D and E
(D)basins, vulnerable to small changes in ocean temperature, occurred over the 20th century and have been rapidly retreating==> HERE WE DONT HAVE THE VERB IN MAIN CLAUSE... and here.OCCURED ==> ACTING AS PAST PARTICIPLE.HENCE THIS ONE IS A FRAGMENT.
(E)basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, and have been rapidly retreating(CORRECT)
KUDOS if it helped.

Hello, raunakd11. Whenever you see and on the GMAT™, you should be thinking of one of three conditions:
1) It is used with a comma before it to join two independent clauses
2) It is used with a comma before it to add the final element of a list
3) It is used without a comma before it, unless that comma ends an embedded phrase or clause, to join two parallel items
In the sentence at hand, the third condition applies in the following manner:
Glaciers that are seated in deep submarine basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, and have been rapidly retreating in the last decades.
The shell of the sentence conveys that glaciers of a certain type are vulnerable and have been rapidly retreating. We cannot join the two parallel elements without and. The comma before the conjunction simply helps to rope off the such as interrupter.
I hope that helps. If you have further questions, feel free to ask.

IMO, E
Glaciers that are seated in deep submarine basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, have been rapidly retreating in the last decades.
(A)basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, have been rapidly retreating
Wrong. The structure is not parallel. X that are seated.....are vulnerable......., have been rapidly retreating.... ==> We need "and" before "have been".
(B)basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, have been rapidly retreated
Wrong. Same as A. X that are seated.....are vulnerable......., have been rapidly retreated....==> We need "and" before "have been".
(C)basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, and are rapidly retreating
Wrong. The meaning is wrong, The Glaciers are not retreating (progressive tense), but they have been retreating (perfect progressive), because the action "retreating" initiated in the past (in last decades).
(D)basins, vulnerable to small changes in ocean temperature, occurred over the 20th century and have been rapidly retreating
Wrong. "occurred...." is not clear. It may modify "changes" or "Glaciers".
(E)basins are vulnerable to small changes in ocean temperature, such as those that occurred over the 20th century, and have been rapidly retreating
IMO, correct. The structure is: X that are seated... are vulnerable.....and have been rapidly retreating.....in the last decades.
Waiting for OA.
