Correct! Displacement is indeed a vector quantity. A vector quantity is a type of physical quantity that has both magnitude and direction. Displacement specifically refers to a change in position and it is described by both the distance moved and the direction in which it has moved. In contrast, scalar quantities, such as magnitude, only have magnitude and no direction associated with them. Dimensional is not the correct answer in this context, as it refers to the physical units in which quantities are measured. So, A. vector is the correct choice.
Yes, your answer is correct. Displacement is a vector quantity.
