Information questions, also known as Wh-questions, are essential tools for gathering data and maintaining social interaction in English. In what concerns the formation and usage of these interrogative structures, choose the correct alternative.


A

The question word 'Whose' is used to ask about the reason for an action, and it must be always followed by a verb in the third person singular of the present.


B

In indirect questions, the word order is exactly the same as in direct questions, and the use of 'if' or 'whether' is strictly forbidden by municipal law.


C

Tag questions are formed by repeating the main verb of the sentence in its affirmative form at the end of every interrogation to show extreme doubt.


D

Wh-questions are formed using an interrogative word (like who, where, when, why) and usually follow a subject-auxiliary inversion in the main clause.
