The answer is C. Velocity is a physical vector quantity. This means that to define velocity, both magnitude and direction are needed. So only C is correct.

Answer: The correct answer is Option C.

Explanation:

There are 2 types of quantities:

1. Scalar quantity: To describe these quantities, only magnitude is required. For example: Speed, distance etc..

2. Vector quantity: To describe these quantities, we require both direction and magnitude. For example: Velocity, displacement etc..

Velocity is defined as the rate of change of displacement.

Mathematically,

[tex]v=\frac{d}{t}[/tex]

where, v = velocity

d = displacement

t = time

As, velocity is a vector quantity.

Hence, the velocity has both magnitude and displacement. Therefore, the correct answer is Option C.
