The passenger said to the clerk, ” When is the next train to Hyderabad?”

The correct answer is A. The passenger asked the clerk when the next train to Hyderabad was.

The passenger used the interrogative pronoun “when” to ask about the time of the next train. The clerk is the person who is in charge of providing information about the train schedule. The passenger is asking for information about the next train to Hyderabad.

B is incorrect because the passenger did not use the word “that”. C is incorrect because the passenger did not use the word “that” and the verb “was” is in the wrong tense. D is incorrect because the passenger did not use the word “that” and the verb “was” is in the wrong tense.
