You're right. The same reason applies to E too.

I don't think there is anything wrong with D. I would pick D as the answer.

Possessive pronouns can refer to possessive nouns. so "her" can refer to "Leakey's contributions".

Option A and E are not parallel and option C is awkward. Option B makes the 2 elements prepositional phrases. But still, B is wrong because these two prepositional phrases are not parallel with eachother("documenting" is not preceded by "her") and with the item at the beginning of the sentence, "her work".

Observe three-way parallelism in D.

In addition to her work on the Miocene hominid fossil record, Mary Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of East African cave paintings.

Hope that helps..

Final solution at one place:

Important: The purpose of this post (and all the other posts by me) is to give a complete solution to all GMAT-Prep Verbal questions at one place. Sometimes students have to wade through dozens of posts to get to the final answer. My posts will give one complete and crisp solution required to arrive at the correct answer by eliminating the wrong one. Some of the content in these posts may have been taken from various other sources (discussion forums).

In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting East African cave paintings.
(A) Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting
(B) Leakey contributed to archaeology by her discovery of the earliest direct evidence of hominid activity and by painstakingly documenting
(C) Leakey was a contributor to archaeology with her discovery of the earliest direct evidence of hominid activity and with her painstaking documentation of
(D) Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of
(E) Leakey's contributions to archaeology include her discovering the earliest direct evidence of hominid activity and painstaking documentation of

A, B: 'discovery' is not parallel to 'documenting'
E: 'discovering' is not parallel to 'documentation'
C: uses the wrong idiom 'was a contributor with' ... completely wrong.

D is correct.

Another version of the same question:

In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology through her discovery of the earliest direct evidence of hominid activity and through her painstaking documentation of East African cave paintings.
A. Mary Leakey contributed to archaeology through her discovery of the earliest direct evidence of hominid activity and through her painstaking documentation of
B. Mary Leakey contributed to archaeology by her discovery of the earliest direct evidence of hominid activity and painstakingly documenting
C. Mary Leakey was a contributor to archaeology by discovering the earliest direct evidence of hominid activity and with her painstaking documentation of
D. Mary Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and painstakingly documenting
E. Mary Leakey's contributions to archaeology include her discovering the earliest direct evidence of hominid activity and painstaking documentation of

B, D: 'discovery' is not parallel to 'documenting'
C, E: 'discovering' is not parallel to 'documentation'

A is correct.

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."
