    Correct option is C)

    Mass of A is m

    If mass A move to a distance x, then spring will stretch to x value. And it will lift the mass of B

    The correct Answer is C

    Solution

    The spring will exert maximum force when the ball is at its lowest position. If the ball has descended through a distance x to reach the position,

    `mgx=(1//2)Kx^2` or `x=2mg//K` (i)

    For the block B to leave contact spring force,

    `Kx=Mg` (ii)

    Comparing Eqs. (i) and (ii), `m=M//2`
