$A$ block of mass $M$ is placed on $a$ horizontal surface and it is tied with an inextensible string to $a$ block of mass, as shown in figure. A block of mass $m_0$ is also placed on $M$ If $\mu < \mu_{min}$ (the minimum friction required to keep the block $m$ stationary), then the downward acceleration of $m$ is

A

$\left[ {\frac{{m - \mu M}}{{m + M}}} \right]g$

B

$\left[ {\frac{{m - \mu ({m_0} + M)}}{{m + {m_0} + M}}} \right]g$

C

$\left[ {\frac{{m - \mu ({m_0} + M)}}{{m + M}}} \right]g$

D

$\left[ {\frac{{m - \mu M}}{{m + {m_0} + M}}} \right]g$
