Correct Answer

My Query:

In the officially correct answer, which is D, How come each and contributing in harmony?

Because contributing is not a verb, but participial form, and "each" requires a bonafide verb. Isn't it?

Also, Please analyse the correct answer, which is E.

"Each contributing" is an absolute phrase, a noun phrase that functions as a modifier but is not itself a clause, and so requires no verb. (Notice that the absolute phrase follows an independent clause, so we don't have to worry about the possibility that we're dealing with a sentence fragment here.)

each of which contribute is incorrect because "each" is a singular subject and "contribute" is a plural verb. Moreover according to their is problematic as the plural possessive pronoun "their" seems to refer to the singular antecedent "each."

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
