Immediacy-The state, condition, or quality of being immediate.Whenever it is time to prepare to talk in class the first thing I think about is how you can connect with the audience. I do this first because I feel that any audience member should feel a connection between them and the speaker whether or not they agree or disagree with the speaker. And the way I display this connection with the audience is through the types of immediacy such as verbal immediacy, nonverbal immediacy, technological influences on immediacy, and cultural influences on immediacy.
In the sentence pattern for asking questions, the subject is placed immediately after the operator (Operator [did, does, was] + Subject) while in the sentence pattern for making statements, the subject is placed before the verb phrase (Subject + VP). However, some statements may be in question form (You've already eaten?) and some questions (such as rhetorical ones) may be in statement form (Haven't you peed already?).
I believe it is B isn't, because if you use the others it most likely sounds like slang.
I believe it’s A.hope this helps!
