What information should you gather before writing an outline?

a. audience, topic, details, and final

b. topic, audience, purpose, and details

c. topic, purpose, details, and outline

d. audience, purpose, and details

I'd say the answer is B. A cannot be correct because how can you gather "final" before writing an outline? C is also not correct because how can you gather "outline" before you write an outline? And D is not correct, because it is missing a "purpose" of the text.
