Answer

Brief Explanation:

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. Speed has only magnitude (e.g., 50 km/h), so it is scalar. Velocity has magnitude and direction (e.g., 50 km/h north), so it is vector.

Answer:

A. Speed is a scalar quantity and velocity is a vector quantity.
