benefits of tea

Most of the purported health benefits of tea comes from antioxidants--compounds also found in beta carotene, vitamin E, and vitamin C that inhibit the formation of plaque along the body's blood vessels.

A) comes from antioxidants--compounds also found in beta carotene, vitamin E, and vitamin C that
B) comes from antioxidants--compounds that are also found in beta carotene, vitamin E, and vitamin C, and they
C) come from antioxidants--compounds also found in beta carotene, vitamin E, and vitamin C, and
D) come from antioxidants--compounds that are also found in beta carotene, vitamin E, and vitamin C and that
E) come from antioxidants--compounds also found in beta carotene, vitamin E, and vitamin C, and they

please explain. i got the answer correct.. but was stuck between c and d initially. OA is D

[Bill@VeritasPrep]

The 2/3 split here is right at the start of the underlined portion: do we need "comes" or "come"? The subject is "most of the purported health benefits," so we need the plural form "come".

We can eliminate E for using the pronoun "they," which could refer to antioxidants, compounds, or health benefits.

D uses parallel construction correctly:

"compounds that (are also found...) and that (inhibit the formation...)"

C does not use parallel form.

IMO: D

so what would option C have to be rewritten as to follow parallel form?

Would it be "compounds also fund in beta carotene, vitamin E, and vitamin C, and ALSO" inhibit..?
