Parallelism hope this helps if not sorry not sorry
I think that the answer is B. ( the 2nd one from the top)
Answer:
- The phrase "art history professor" should be set of with commas
Explanation:
the subject in this sentence is "Valentine's mother" "an art history professor just renames the or further describes the subject, ("an art history professor" is talking about "Valentine's mother") therefore it should be separated with commas.
I hope this helps you :)
