Brownian motion is a/an

Assertion: The Brownian movement is due to the bombardment on colloidal particle by the molecules of dispersion midium which are in the constant motion like molecules in a gas. Reason: Brownian movement provides a visible proof of the random kinetic motion of molecules in a liquid.
