The correct answer is option 'C', which is plaster.

Stucco is a type of plaster that is commonly used to cover walls and ceilings. It is a decorative material that is applied to the surface of walls and ceilings to create a smooth and durable finish. Stucco is made from a mixture of cement, sand, and water, along with other additives such as lime or acrylics.

Stucco has been used for centuries in various cultures around the world. It has been used in ancient Egyptian, Greek, and Roman architecture, as well as in many other historical buildings. Stucco is known for its durability and resistance to weathering, which makes it an ideal choice for exterior surfaces.

Stucco is typically applied in multiple layers. The first layer, called the scratch coat, is applied directly to the surface of the wall or ceiling. This layer provides a rough surface for the subsequent layers to adhere to. The second layer, called the brown coat, is applied over the scratch coat to provide additional strength and stability. Finally, the finish coat is applied to create the desired texture and appearance.

Stucco can be finished in various ways, depending on the desired look. It can be smooth, textured, or even sculpted to create intricate designs. Stucco can also be painted or colored to match the desired aesthetic of the building.

In addition to its decorative purpose, stucco also provides practical benefits. It helps to insulate buildings by providing an additional layer of protection against heat and cold. Stucco is also fire-resistant, which makes it a safe choice for buildings.

Overall, stucco is a versatile and durable material used for plastering walls and ceilings. Its history and long-standing use in architecture demonstrate its effectiveness and popularity as a building material.
