Option D seems plausible, but I'd need to do some calculations to be sure. Maybe I can borrow a calculator from the person next to me.

I disagree with option A. Unequal observations? That's no big deal, we're data scientists, not magicians.

Hmm, I'm not sure about option B. Paired T-test? That sounds like a fancy dance move, not a statistical analysis technique.
