    First read the solution, then read this comment. Here you need to check for two points, at t=0 and at some time t=π/2w(this is chosen such that everything cancle and just π/2 remain). These two points are showing a movement from point A to B with increase in time. This means the rotation is anticlockwise. Now it's homework time for you, do the same calculations for option B. there you can take alpha=0(you can do that, because it will never change your results (as relative phase remains same between Bita and alpha). Best regards.

    I was expecting this question from you. it should be asked by a curious student which you are! Now refer to my comment next comment about the sense of rotation, and let us talk about anticlockwise(as specified by you).

    Here both option B and C could be the answer. Because they haven't specified sense of rotation. see the attached for better understanding. I am sure you will get what I am trying to say. Best regards.
