The correct answer is: E. No error
The sentence “The student answered to the question asked by the Inspector” is grammatically correct. The word “answered” is a verb that takes a direct object, which is the word “question”. The word “asked” is a participle that modifies the noun “question”, and the word “by the Inspector” is a prepositional phrase that modifies the verb “asked”.
The sentence can be rewritten as follows:
- The student answered the question.
- The question was asked by the Inspector.
- The student answered the question that was asked by the Inspector.
The sentence is also grammatically correct if the word “to” is removed. The word “to” is a preposition that can be used to indicate the recipient of an action. In this case, the action is “answering”, and the recipient is “the question”. However, the word “to” is not necessary in this sentence, and it can be removed without changing the meaning of the sentence.
