Which quantity is a scalar quantity? a. acceleration b. area c. displacement d. force e. velocity

Area is the scalar quantity,

The correct answer is option B.

Explanation:

Scalar quantity are those which only have magnitude and no direction.

For example:  mass, time, distance etc.

Vector quantity are those which have  both magnitude and direction.

For example:  displacement , velocity etc.

From the given options, the quantity which is scalar is are a because it only has magnitude but no directions.

Where acceleration, velocity, displacement  and force all are vector quantities.

Hence, the correct answer is option B.
