In figure, two blocks $M$ and $m$ are tied together with an inextensible and light string. The mass $M$ is placed on a rough horizontal surface with coefficient of friction $\mu$ and the mass $m$ is hanging vertically against a smooth vertical wall. The pulley is frictionless. Choose the correct statement $(s)$ related to the tension $T$ in the string

AWhen $m < \mu M, T = mg$

BWhen $m < \mu M, T = Mg$

CWhen $m > \mu M, \mu Mg < T < mg$

DBoth $(A)$ and $(C)$
