A block of mass \( m \) is attached with a massless spring of force constant \( k \). The block is placed over a rough inclined surface for which the coefficient of friction is \( \mu=\frac{3}{4} \). The minimum value of \( M \) required to move the block up the plane is (Neglect mass of string and pulley and friction in pulley) :
(A) \( \frac{3}{5} m \)
(B) \( \frac{4}{5} m \)
(C) \( 2 m \)
(D) \( \frac{3}{2} m \)
