C

Idiomatic construction

Not only X but Also Y

X and Y must be parallel. Only C offers it

Temporary-employment agencies benefit not only from the increasing demand for clerical workers but also from the requests for highly paid professionals, who make higher profits for the agencies when placed and whose requests have increased in the recent wave of corporate takeovers.

i also got C, but OA given is : E

it should be 'request for whom' and not 'whose requests'

which sounds like highly paid professionals' requests

In E it is concise and modifiers correctly placed.

Not only but also is the correct idiom

Boils down to c,d,e

As Sudeep rightly pointed out "whose request" chenges the intended meaning of the senetence.

So E

Parallel construction:

NOT ONLY FROM increasing demand (for cleriucal workers)
BUT ALSO FROM higher profits (made in placing highly paid professionals)

agree with sudeep_ar E should be correct.
