Viscosity question

  1. Jan 31, 2010 #1
    The question is attatched. The question is number 8.

    I simply do not understand, if the question is right at all, because I believe that options A and D are both correct. But, B it seems is the answer. High temp means low visc. and vice versa, leading to A and D being correct.

    Please explain why B is correct

    Low viscosity means higher terminal velocity. (Less resistance)
    High viscosity means lower terminal velocity.
    Only one option can be right.
