Correct option is D
Both
evaporation of water and
sublimation of dry ice are
endothermic processes.
Evaporation of water requires the absorption of heat from the surroundings to convert liquid water into water vapor.
Sublimation of dry ice (solid CO₂ directly turning into gas) also absorbs heat from the surroundings, causing the solid to change into a gas without passing through the liquid phase.
In both processes, heat is absorbed from the surroundings, making them endothermic. On the other hand, the
dilution of sulphuric acid is an exothermic process, as it releases heat
