Select the most appropriate option that can substitute the highlighted words in the given sentence.
Adi had not only assisted her by giving evidence in the case but also provided many examples to prove her point in the court.

Correct option is D

The correct substitution of the highlighted words is ‘assisted her not only by’ to make the sentence grammatically and contextually correct.
Explanation:
· The phrase "not only... but also" is a correlative conjunction and should be placed properly for parallelism.
· The correct placement ensures that the phrase "not only by giving evidence" is parallel to "but also provided many examples."
· The correct sentence structure should be: "Adi assisted her not only by giving evidence in the case but also provided many examples to prove her point in the court."
Grammatical rule used:
· When using "not only... but also", the words following each part of the conjunction must be grammatically parallel.
· Example:
· ✅ "She is not only intelligent but also hardworking." (Correct parallelism)
· ❌ "She is not only intelligent but also she works hard." (Incorrect)
Meanings of other given options and why they are incorrect:
· (a) assisted her only not by – Incorrect word order and incorrect use of "only not by".
· (b) assisted not only by her – Changes the meaning entirely, implying someone else was assisted.
· (c) assisted not only her by – Incorrect word placement, disrupts sentence clarity.
