Which one of the following is a vector quantity ?

A vector quantity has both magnitude and direction; scalars have only magnitude. Momentum is defined as mass times velocity, and because velocity is directional, momentum also carries direction and is therefore a vector quantity. By contrast, pressure is defined as force per unit area and is treated as a scalar field (it has magnitude at a point but no associated direction) [1]. Similarly, energy and work are scalar quantities: they have magnitude but no intrinsic direction and are listed as scalars in standard classifications [1]. Hence among the options given, momentum is the vector quantity.
