Question Analysis
This question involves linking phase changes to changes in disorder (entropy). The main focus is on understanding the relationship between phase order and entropy.

Key Concept Explanation
Entropy is a measure of the disorder or randomness of a system. The entropy of phases increases in the order:Solid < Liquid < Gas
Phase changes to a more disordered state (solid→liquid→gas) increase entropy.
Phase changes to a more ordered state (gas→liquid→solid) decrease entropy.

Step-by-Step Solution
1. Recall the entropy order of phases: Solid (lowest) < Liquid < Gas (highest).
2. Identify which option involves a transition to a more ordered state (decreased entropy):
A. Solid→Liquid (increase entropy, eliminate)
B. Solid→Gas (increase entropy, eliminat...
