• A. A-4, B-3, C-1, D-2
• B. A-4, B-1, C-3, D-2
• C. A-2, B-1, C-3, D-4
• D. A-2, B-3, C-1, D-4

Answer 1

The correct option is A A-4, B-3, C-1, D-2

Heating Camphor - Sublimation- Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.

Cooling of water vapour up to room temperature - Condensation - Condensation is the process of a substance in a gaseous state transforming into a liquid state.

Cooking an egg - Chemical change

Formation of water vapour at room temperature - Evaporation - Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure
