A. of Lewis Latimer and Thomas Edison, who became known for his invention of the light bulb,
- when "who" follows "Lewis Latimer and Thomas Edison", it should modify both of them. Since it continues "his invention," we must rearrange the sentence so that we're only modifying Thomas Edison.

B. of Lewis Latimer and Thomas Edison, known for his invention of the light bulb,
- same issue as in A. "known for" is modifying both men here.

C. of Thomas Edison, known for his invention of the light bulb, and Lewis Latimer
- the modifier is correctly modifying just "Edison"

D. of Lewis Latimer and Thomas Edison became known for his invention of the light bulb and
- same issue with "his" applying to both men
- the structure of the sentence is now "the research... became known for... and accelerated..." This is nonsensical. Edison was known for the lightbulb; the research accelerated development.

E. that was conducted by Thomas Edison, who became known for his invention of the light bulb, and Lewis Latimer
- unnecessarily wordy. This fixes the modifier issues of A, B, and D, but C gets the same information across more succinctly, without unnecessary tense makers such as "was conducted" and "who became known."

The answer is C.

"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."
