idiom usage is Not only X but also Y . here X and y needs to be parallel. Additionally relative clause  that a fruit is  will be repeated with both X, and Y and it must make sense with X, and Y

(A) prevents against heart disease - X, and Y are not parallel x is a noun phrase, whereas Y contains verb (prevents). Also it has meaning error, we can omit not only, and but also from the sentence to see the meaning error

same goes with B, C and E

Look for an option which is an adjective and is parellel with the sentence
Hence D is the right answer
