The correct answer is D. Work.
A vector quantity is a quantity that has both magnitude and direction. Heat, angular momentum, and time are all scalar quantities, which means they only have magnitude. Work is a vector quantity because it has both magnitude and direction. The direction of work is the same as the direction of the force that is applied.
Heat is a form of energy that is transferred from one object to another due to a difference in temperature. The amount of heat transferred is proportional to the difference in temperature and the mass of the objects. Heat is a scalar quantity because it only has magnitude.
Angular momentum is a quantity that is used to describe the rotation of an object. It is equal to the product of the mass of the object, the radius of the object’s rotation, and the object’s angular velocity. Angular momentum is a scalar quantity because it only has magnitude.
Time is a measure of the interval between two events. It is a scalar quantity because it only has magnitude.
