A. Transitional Motion
B. Rotational Motion
C. Brownian Motion
D. Oscillatory Motion
Correct Answer:
Option C – Brownian Motion
Explanation
Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations.
If a number of particles subject to Brownian motion are present in a given medium and there is no preferred direction for the random oscillations, then over a period of time the particles will tend to be spread evenly throughout the medium.
