Answer: A.
Explanation:
Brownian motion is the random motion of a particle as a result of collisions with surrounding gaseous molecules. Diffusiophoresis is the movement of a group of particles induced by a concentration gradient. This movement always flows from areas of high concentration to areas of low concentration.
Example: The movement of pollen grains on still water. Motion of dust motes in a room (though largely influenced by air currents).
Electrons are found in the cloud that's surrounded the nucleus of an atom
