    B. Momentum is a vector quantity and kinetic energy is a scalar quantity.

    Explanation:

    A scalar quantity has just magnitude. A vector quantity has both magnitude and direction.

    Momentum is the product of mass and velocity.

    P = m v

    It is a vector quantity. It depends on magnitude as well as direction.

    Energy possessed by a body due to virtue of its motion is known as kinetic energy. It is a scalar quantity.

    E = 0.5 mv²

    Thus, the correct option is A.
