Becca????????? I think, that's confusing
Pretty sure the first one
D. Points that elicit an emotional response
My friend, Alex, plays tennis.
My = possessive pronoun
friend = subject
Alex = an appositive (which is a noun that renames another noun right beside it) -- though not an adjective, it functions like one to explain which friend
plays = verb
tennis = direct object
hope this helps :)
