Im not sure for question 1.
And I think number 2 is C but correct me on that. Author use a characters personality or personalities trough their speech, the way the characters talk and the way they act. Questions can be asked like is this person amiable or arrogant. It can also be as of apperance what the character looks like. If they are tall, short, skinny, chubby, strong, weak, brunette, blond ext. Descriptions in most stories are used to give an imagination of what a characters looks or seems like.
