Answer»

Right answer is (c) Plaster

To explain I would SAY: The most common types of plaster mainly contain either gypsum, lime, or cement, but all WORK in a similar way. The plaster is manufactured as a DRY powder and is mixed with water to form a stiff but workable PASTE immediately before it is applied to the surface. The reaction with water liberates HEAT through crystallization and the hydrated plaster then hardens.
