A double star system consists of two stars A and B which have time periods `T_A` and `T_B` radii `R_A` and `R_B` and masses `M_A` and `M_B`. Choose the correct option:

A

If `T_A gt T_B`, then `R_A gt R_B`

B

If `T_A gt T_B`, then `M_A gt M_B`

C

`(T_A // T_B)^2 = (R_A // R_B)^3`

D

`T_A = T_B`
