Answer: The correct answer is "scalar".
Explanation:
Scalar quantity: It is a physical quantity. It has magnitude only. For example, mass is a scalar quantity.
The mass of the object is 3 kg.
Speed is a scalar quantity. A car is travelling with the speed of 70 km/s.
Vector quantity: It is a physical quantity. It has magnitude as well as direction. For example, velocity is a vector quantity.
A car is travelling with 60 km/s speed in north direction.
Speed + direction= velocity
Therefore, a quantity that has magnitude only is a scalar.
