Figure shows a uniform smooth solid cylinder `A` of radius `4 m` rolling without slipping on the `8 kg` plank which, in turn, is supported by a fixed smooth surface. Block `B` is known to accelerate down with `6 m//s^(2)` and block `C` moves down with acceleration `2 m//s^(2)`.

What is the angular acceleration of the cylinder?

A

`(4)/(5)"rad s"^(-2)`

B

`(6)/(5)"rad s"^(-2)`

C

`2"rad s"^(-2)`

D

`"1 rad s"^(-2)`
