Which statement about audience or purpose is true?

audience and purpose are decided on during the prewriting stage.

audience is predetermined before you write, while purpose is not.

the purpose for a piece of writing becomes clear after you begin writing your first draft.

it is safe to assume that the audience for your writing will have the same background knowledge of a subject that you do

I thinks it's A.)Audience And Purpose Are Decided On During The PreWriting Stage.

Refute it, showing why it is mistaken—an apparent but not real problem; acknowledge its validity or plausibility, but suggest why on balance it's relatively less important or less likely than what you propose, and thus doesn't overturn it; concede its force and complicate your idea accordingly—restate your thesis in a more exact, qualified, or nuanced way that takes account of the objection, or start a new section in which you consider your topic in light of it. this will work if the counterargument concerns only an aspect of your argument; if it undermines your whole case, you need a new thesis.
