I need help with these five questions. Please

Which of the following is an example of an author’s purpose for using first-person point of view?

Ow does the author reveal katina's initial excitement about her internship? a) by showing how katina responds to conflict b) by describing how katina felt at the end of the day c) by showing how katina interacts with other characters d) by describing how katina selected her clothes with care

If the author's last name is mentioned in the sentence, it does not need to be included in the in-text citation.
