I had C on my first try. I understand the S-V agreement, but how is the parallelism in place here?

(E)

Reveal not only A but also B is the correct form.

In other choices ||ism is broken by saying "Not only reveal A but also <needed>"

I think the options B, C and D breaks the parallelism rule. Not only X but also Y, X and Y should be parallel. A and E both have parallel X and Y but they A is incorrect due to its faulty S-V agreement (Changes .... reveals), Hence I picked E
Pls correct me if I am wrong
