Block A of mass 5 kg is resting on a frictionless floor. Another block B of mass 7kg is resting on it as shown in the figure. The coefficient of friction between the blocks is 0.5 while kinetic friction is 0.4. If a force of 100 N is applied to block B, the acceleration of the block A will be `( g =10 ms^(-2))` `:`

A

`0.8 ms^(-2)`

B

`2.4 ms^(-2)`

C

`0.4 ms^(-2)`

D

`4.4 ms^(-2)`
