Correct Answer: Fusion

Solution : The correct option is Fusion .

The melting process is also known as "fusion". Melting, also known as fusion, is the phase transition in which a solid substance becomes a liquid owing to a rise in temperature. During melting, the particles absorb enough heat energy to overcome the forces keeping them together, allowing them to move more freely and transform into a liquid. For example, fusion or melting occurs when a solid ice cube turns into liquid water when it absorbs heat.
