At absolute zero ( 0 K or −273.15∘C ), the particles of matter:

A. Vibrate in fixed positions
B. Stop moving
C. Move at the speed of light
D. Undergo fusion
Answer: Option B
Solution (By JKSSB Mock Tests Team)
In classical thermodynamics, absolute zero (0 K) represents the lowest theoretical limit of temperature, where all thermal motion of particles effectively ceases. While quantum mechanics dictates they still retain a tiny 'zero-point energy,' macroscopic kinetic movement completely stops.
