The answer is B
Because it is proved from a topic in vectors that
Work is a dot product between the force and displacement
W = F™ • D™
™ Means that both are vectors
When we dot multiply two vectors we have a scalar.
Physical quantities specified completely by giving a number of units (magnitude) and a direction are called vector quantities. Examples of vector quantities include displacement, velocity, position, force, and torque.
Vector quantity are quantity that has magnitude but no direction.
Work (is the product of force and the distance moved in the direction of that force ), hence it is a scalar quantity since it has both magnitude and direction.
