SAT writting grammar HELP!!!!

The three sections of my neighbor’s newly A(planted garden), each B(totally different) in design and composition, C(harmonizes) with D(one another) in color and texture.E(no error)

Why is the answer D? CAn someone please write down the correct form and the rule. Thanks in advance

“writing grammar”

My guess would actually be C. If you take out the “each” clause, which is NOT connected to the main verb “harmonizes,” you get “The three sections harmonizes,” which is not correct.

To clarify, I think either the given “correct answer” is a mistake, or you copied the sentence wrong here.

I agree it should be C. “each…composition” is an interrupting phrase, and therefore, should not be taken into account when conjugating the verb.

Yes, C is the only reasonable answer.

Wow You are really good! I rechecked the answers and the answer was “C” Thank you so much!
