Solution

The correct option is B
P:- Solidification

Q:- Melting

P:- Solidification

The phase transition from liquid to the solid state on cooling or removing heat is called solidification. Conversion of water (liquid) to ice (solid) is an example of solidification.

Q:- Melting

The phase transition from solid to the liquid state on heating is called melting. Conversion of solid (ice) to water (liquid) is an example of melting.
