What poem are u talking about??
An appositional phrase is any phrase that repeats a noun, often with a name and then with a title. IN this case, it would be "my dad" and "a basketball coach".
C and D, making a more humorous casual speech will help the performance and will make it easier to connect with the speaker.
I think that would be C because you still want to have a good essay! Hope i helped! :)
