Hey there!
Your answer is option A.
"Molecules of the dispersion medium colliding with dispersed phase particles" is what causes Brownian motion in colloids.
Hope this helps you.
Have a great day!
What's the problem ? Hardness is not the definition of a metal.
You need to expand your thinking. EVERY element is solid, liquid, and gas, over different ranges of temperature ... including all of the metals. There are only TWO elements that are liquid AT ROOM TEMPERATURE, and mercury is one of them. But on a mild day at the south pole, mercury is solid too.
