In the figure shown all the contacts are smooth. Strings and spring are light. Initially 'A' is held
\( \mathrm{P} \) by someone and ' \( \mathrm{B} \) ' and ' \( \mathrm{C} \) ' are at rest. Masses of \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are \( \mathrm{M}, \mathrm{M} \) and \( 2 \mathrm{M} \) respectively. Then W just after the block 'A' is released which of the following statements are correct :-
(I) Acceleraion of block \( A \) is \( \frac{g}{2} \)
(II) Acceleration of block B is zero
(III) Acceleration of block \( \mathrm{C} \) is zero
(IV) Acceleration of block B is \( \frac{\mathrm{g}}{2} \)
(1) I \& IV
(2) I, II \& IV
(3) I, III \& IV
(4) All are correct
