Three blocks `A`, `B` and `C`, whose masses are `9kg`, `9kg` and `18kg` respectively as shown in the figure, are released from rest. The co-efficient of friction between block `A` and the horizontal surface is `0.5` & the co-efficient of friction between block `B` and the horizontal surface is `0.5`. Find the acceleration of block `C` just release [Take `g=10m//s^(2)`]. All strings and pulleys are ideal

A

`(30)/(9)m//s^(2)`

B

`(50)/(9)m//s^(2)`

C
