The correct answer is: A. Granite.
Granite is a hard, igneous rock that is often used for monumental buildings. It is composed of quartz, feldspar, and mica, and it can be found in a variety of colors, including pink, gray, and black. Granite is a durable stone that can withstand the elements for centuries, making it an ideal choice for buildings that are meant to stand the test of time.
Marble is a metamorphic rock that is formed when limestone is subjected to heat and pressure. It is a relatively soft stone that can be easily carved and polished, making it a popular choice for sculptures and other decorative objects. However, marble is not as durable as granite and is more susceptible to weathering and damage.
Sandstone is a sedimentary rock that is formed from sand grains that have been cemented together. It is a relatively soft stone that can be easily eroded, making it not a good choice for monumental
buildings.Slate is a metamorphic rock that is formed when shale is subjected to heat and pressure. It is a relatively hard stone that can be split into thin sheets, making it a popular choice for roofing and other applications where a
flat surface is required. However, slate is not as durable as granite and is more susceptible to weathering and damage.
