Two particles A and B are moving in uniform circular motion in concentric circles of radii `r_(A)` and `r_(B)` with speed `u_(A)` and `u_(B)` respectively. Their time period of rotation is the same. The ratio of angular speed of a to that of B will be:

A

`1:1`

B

`r_A:r_B`

C

`v_A:v_B`

D

`r_B:r_A`
