Correct option is B
An endothermic process is a chemical reaction or physical change that absorbs energy from its surroundings, usually in the form of heat. Both sublimation of dry ice (which is the transition from solid carbon dioxide directly to gas) and evaporation of water (which is the transition from liquid to gas) are endothermic processes because they require the absorption of heat to occur. The energy absorbed in these processes is used to overcome the forces holding the molecules together in the solid or liquid state, allowing the transition to a gaseous state.
