A round disc of moment of inertia `I_2` about its axis perpendicular to its plane and passing through its centre is placed over another disc of moment of inertia `I_1` rotating with an angular velocity `omega` about the same axis. The final angular velocity of the combination of discs is.

A

`(I_2omega)/(h+h)`

B

`omega`

C

`frac(I_1omega)(I_1+I_2)`

D

`frac((I_1+I_2)omega)(I_1)`
