The correct option is E A
Let’s examine the sentence: “He plays neither now nor promises to play later.” The sentence uses correlative conjunction, “neither…nor.” Correlative conjunctions come in pairs and join equal items together. Also, the clauses or phrases followed by “neither” and “nor” are parallel in structure. So, if “neither” is followed by a noun, “nor would also be followed by a noun. If “neither” is followed by a verb, “nor would also be followed by a verb and so on. In the given sentence, “nor” is followed by the verb “promises” and so, “neither” would also be followed by the verb. Therefore, the verb “plays” would move after “neither.” So, the correct sentence would be, “He neither plays now nor promises to play later.” So, the error is in Part A of the sentence. Hence, Option A is the correct answer.
