Question

Most of the purported health benefits of tea comes from antioxidantscompounds also found in beta carotene, vitamin e, and vitamin c that inhibit the formation of plaque along the bodys blood vessels.

Answer 1

Hope it may be helpful

The subject of the first part is - most (of the health benefits)- and the verb is – come -. By default, the subject of the second part is -( most ) of the health benefits -and its verb – Inhibit.

You can see the distortion of the meaning that it is the purported health benefits that inhibit plaque rather then the anti-oxidants. This is why C is not the right choice.

In E, the pronoun they may refer to the health benefits since subject rightly takes priority over any other noun that is placed nearer than the subject, per se.
