Detailed Solution

The random movement of particles suspended in a medium is known as brownian motion .
This pattern of motion often entails a particle moving to a different sub-domain after experiencing random variations in its position within a fluid sub-domain
The colloidal particle moves in a zigzag pattern as a result of the dispersion medium's molecules having an uneven impact on it

Hence, the correct option is A.
