Hi there!
Your answer will be B. No, because the speaker claims that homework doesn't help students learn but the evidence doesn't support.
Step-by-step explanation:
Eliminate A and C because that is not efficiant or strong evidence of WHY it is or isn't relevant. Eliminate D because it does not provide a thorough explanation of WHY it should or shouldn't be banned.
Hoping this makes sense and is helpful. Have a good day! :)
