Pick up the correct statement from the following: A. Soft stones are required for carving B. Light stones are required for arches C. Hard stones are required to stand high pressure D. All the above

The correct answer is D. All the above.

Soft stones are easier to carve than hard stones, so they are often used for sculptures and other decorative objects. Light stones are less dense than heavy stones, so they are often used for arches and other structures that need to be supported by a strong but lightweight material. Hard stones are able to withstand high pressure without breaking, so they are often used for building materials and other applications where strength is important.

Here are some examples of each type of stone:

• Soft stones: marble, limestone, sandstone
• Light stones: granite, marble, travertine
• Hard stones: granite, marble, quartzite

It is important to note that these are just general guidelines, and there are many exceptions. For example, some types of marble can be quite hard, while some types of granite can be quite soft. The specific properties of a stone will depend on its composition and structure.
