pressure defines as the force per unit area.

Answer: Option (B) is the correct answer.

Explanation:

Pressure is a defined as force per unit area.

Mathematically,      Pressure = \(\frac{Force}{Area}\)

Pressure does not depend on the number of particles of a substance or matter and inside or outside the container. It only get affected by the force acting between the number of particles in a given unit area.

Thus, we can conclude that out of the given options, a measure of the force of the collision of particles on a unit area best defines pressure.
