    The correct answer is d*h + 0.20s. I'm guessing there's a typo in the set of answer choices.

    Yes, dh + 0.2s (or some equivalent)

    The correct answer is not in the list, for whatever reason.

    Definitely a typo. I'm guessing the answer is supposed to be (b) but somehow the "h" got deleted.
