<reasoning>

Analyze the particle behavior described

The process describes particles changing from a fixed position (solid state) to becoming mobile within a confined space (liquid state).

Identify the corresponding physical process

The transition from a solid (fixed positions) to a liquid (mobile within a confined volume) is melting.

Match with the given options

Melting corresponds to process C.
