2. Relevant equations

I think a relevant eqn would be v=wr.

3. The attempt at a solution

I think answer is option A since Va/Vb=WRa/WRb.
Is it correct? if not what is the right answer?

No, not correct. There's no $\omega$ values given in the problem statement. There's a big hint in the title of your thread.
