In the arrangement shown in the figure mass of the block \( B \) and \( A \) are \( 2 \mathrm{~m}, 8 \mathrm{~m} \) respectively. Surface between \( B \) and floor is smooth. The block \( B \) is connected to block \( C \) by means of a pulley. If the whole system is released then the minimum value of mass of the block \( C \) so that the block \( A \) remains stationary with respect to \( B \) is: (Co-efficient of friction between \( A \) and \( B \) is \( \mu \) and pulley is ideal)
(a) \( \frac{m}{\mu} \)
(b) \( \frac{2 m}{\mu+1} \)
(c) \( \frac{10 m}{1-\mu} \)
(d) \( \frac{10 m}{\mu-1} \)
