$A$ small ball $B$ of mass $m$ is suspended with light inelastic string of length $L$ from $a$ block $A$ of same mass $m$ which can move on smooth horizontal surface as shown in the figure. The ball is displaced by angle $\theta$ from equilibrium position & then released. Maximum velocity of block during subsequent motion of the system after release of ball is

A

$[gl (1-cos\theta )]^{1/2}$

B

$[2gl(1-cos\theta )]^{1/2}$

C

$[glcos\theta ]^{1/2}$
