Solution

The correct option is B They become solid
In sublimation, a solid object changes directly into a gas on absorbing heat. Similarly, on cooling this gas directly gets converted to solid state. This process is called deposition. Camphor is known to sublimate. On cooling camphor vapours, they become solid.
