$A$ 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 $M$ The minimum value of $\mu$ between the block $M$ and $m_0$ (taking horizontal surface frictionless) for which all the three blocks move together, is

A

$\frac{m}{{m + {m_0} + M}}$

B

$\frac{m}{{m + M}}$

C

$\frac{{{m_0}}}{{m + {m_0} + M}}$

D

none of these.
