Answer 1

Hint:A sentence that asks a question is an interrogative sentence. In grammar, the term is used to refer to features that form queries. An interrogative sentence is, therefore, a phrase whose grammatical form indicates that it is a query. Such sentences can show a grammatical interrogative mood.

Complete answer:
The sentence offers data about something. The word for what is used to ask about such details.The rest ask about the person, the reason or the time.

(a) The typical form (structure) of an interrogative sentence is:
(i) Auxiliary verb +subject+main verb
Do you speak English?
(ii) Main verb BE + subject
Were you cold?
 If we use a WH- word it usually goes first:
(iii) WH-word auxiliary verb subject + main verb
When does the movie start?
The final punctuation is always a question mark (?).

(b) An interrogative sentence's basic function (job) is to ask a direct question. It asks us something or asks us for details (as opposed to a declaration that tells us something or offers information). Interrogative phrases involve a response.

(C) In spoken and written language, we often use interrogative sentences. They are one of the most common forms of sentences. Here are some extremely common interrogative sentences:
Is it cold outside?
Are you feeling better?

(d)Since the time is not mentioned when is the wrong usage.

Hence the correct answer is option ‘B’.

Note: Interrogative sentences have a specified format we have to understand that format to give the answer correctly.
