    Spring C

    Explanation:

    According to Hooke's law, a force require to compress or extend a spring is directly proportional to the distance from its mean position.

    The force of compression or expansion of the spring is given by the formula,

    F = k x

    Where,

    k - spring constant. It is the constant value of the particular spring

    x - distance of expansion or compression from mean position.

    The x value of different spring,

    A = 25 cm

    B = 10 cm

    C = 100 cm

    D = 1 cm

    The highest value of x for the same mass has the smallest spring constant according to the equation.

    Hence, C has the smallest spring constant.
