Here are the essential concepts you must grasp in order to answer the question correctly.
Entropy
Entropy is a measure of the disorder or randomness in a system. In thermodynamics, it quantifies the number of microscopic configurations that correspond to a thermodynamic system's macroscopic state. Higher entropy indicates greater disorder and a higher number of possible arrangements of particles, while lower entropy suggests a more ordered state.

States of Matter
The states of matter—solid, liquid, and gas—differ in their entropy levels. Solids have the lowest entropy due to their fixed, orderly arrangement of particles. Liquids have higher entropy as particles are more mobile, and gases exhibit the highest entropy due to their free movement and vast spacing between particles, allowing for numerous configurations.

Thermodynamic Processes
Thermodynamic processes involve changes in energy and matter that can affect a system's entropy. For example, when a solid melts into a liquid or a liquid vaporizes into a gas, the entropy of the system increases. Understanding these processes helps in ranking different situations based on their entropy, as transitions to more disordered states correspond to higher entropy values.
