option 1 is correct.
We need to be careful in answering the questions to look at whether speed is asked or velocity. We know that angular velocity ω = 2∏ / T. It does not depend on the radius. So in both cases, the angular velocity is the same.
However, in case of angular speed, the particle at the edge has more speed than the particle near the centre.
Let the radii of the tracks be R1 and R2 respectively; Time period in both cases is T while the angular speed could be (Angular speed)1 and (Angular speed)2 respectively.
if we take A1 = 2 ∏ R1 / T and A2 = 2 ∏ R2 / T
Ratio of angular speeds A1 / A2 = R1 / R2
