No.
A sentence always starts with a noun or a pronoun and in some cases it is started by 'It' and 'There' as subject.
'Who' and 'What' are the question words and also they are used as pronouns.
No, a subject in a sentence typically refers to the person or thing that performs the action of the verb. It does not ask the questions "who" or "what." The subject is usually a noun or pronoun.
Example sentence - It is easy to ask questions to avoid getting into trouble.
To locate the subject of a sentence, identify who or what the sentence is about. The subject is usually a noun or pronoun that performs the action of the sentence. Look for the main verb in the sentence and ask "Who or what is doing the action?" to determine the subject.
Ask is always a verb. If ask is used at the beginning of a sentence then the sentence would be an imperative sentence/question. Ask Jon to stop the noise. This is an imperative question because there is no subject. The subject is implied/suggested. The subject is 'you'. (You) ask Jon to stop the noise.
