You need a "from" for parallelism. Discard A and B.

Also you need something parallel to "increasing demand for clerical
workers". So, discard D.

C incorrectly says that agencies benefit from the requests for
highly paid professionals and also has an awkward construction for
the remainder of the sentence

E has good parallelism and uses correct form "whom"

I think the answre should be E...since thats the only construction which maintains parallellism...

from the increasing demand....from the higher profits made
