OFFICIAL EXPLANATION

• I see no errors
• Unlike options C and D, in this sentence, when the nonessential clause is removed, the sentence makes sense
• This option correctly describes two actions in the past:
(1) Rogers and Hammerstein worked with other partners; and
(2) Rogers and Hammerstein became a team.
The use of past perfect ( had collaborated ), a tense that is used to convey the earlier of two past events, is correct.

The answer is E

COMMENTS

I will post the other OE within 12 hours.

KaramveerBakshi  and  Varunsawhney8  , welcome to SC Butler.

Many more people than I anticipated saw right through option D, btw.

Someone asked the other day whether I write these SC questions.
No, not these ones that I post on Butler.

I do spend many long hours looking for them, though.

Writing SC questions is a Herculean task. You should try writing one.
GMAC spends thousands of dollars to produce one SC question.

These answers range from good to excellent. 
Those of you who take a few words to explain what you mean make learning easier for aspirants to follow. Well done.

Error in option A 
Before they became a team, Richard and Oscar wrote....and collaborating...
-'Wrote & collaborating' is not parallel

Option B,C and D is incorrect. 
(SV error: What's the verb of Roger and Oscar? There's no IC)

Option E is the correct answer. 
-No SV error
-To link sequence of related events in past, we need to use past perfect for earlier event and simple past for later event.

I have one question.
Before keyword is already informing us about an event in the earlier past. 
Do you think we would still need past perfect construct here ??
