Correct Answer: Option B
Explanation

Melting (I): This process involves the breaking of intermolecular forces as a solid turns into a liquid, reflecting the molecular structure of matter.

Boiling (II): Similar to melting, boiling involves the transition from liquid to gas, indicating how molecules gain energy and move apart

Conduction (IV): This is the process of heat transfer through collisions between molecules, demonstrating how molecular interactions lead to energy transfer.

There is an explanation video available below.
