The correct answer is: Brownian movement is more pronounced for smaller particles than for bigger-particles.
Brownian movement is the random motion of particles suspended in a fluid (liquid or gas), resulting from their collision with the fast moving atom or molecules in the liquid or gaseous state of the matter. That means, smaller particles are responsible for the Brownian movement.
