Explanation:

Sedimentary rocks are formed from the accumulation and compaction of sediments over time. These rocks are commonly found near bodies of water such as rivers, lakes, and oceans. They are an important resource in construction and are used in making bricks and cement.

Among the given options, shale is the correct answer. Here's why:

Shale:
- Shale is a fine-grained sedimentary rock composed mainly of clay minerals.
- It is easily split into thin layers and has a laminated appearance.
- Shale has excellent properties for making bricks and cement.
- When shale is heated, it can be transformed into a substance known as "clinker," which is an essential ingredient in cement production.
- The clinker is then ground into a fine powder and mixed with other materials such as gypsum to produce cement.
- Shale bricks are also highly durable and can withstand high temperatures, making them suitable for construction purposes.

Other options:

- Conglomerate: Conglomerate is a sedimentary rock composed of rounded gravel-sized particles. It is not commonly used in making bricks and cement.
- Sandstone: Sandstone is a sedimentary rock composed of sand-sized grains. While sandstone can be used in construction, it is not as commonly used in making bricks and cement compared to shale.
- Limestone: Limestone is a sedimentary rock composed mainly of calcium carbonate. It is widely used in the production of cement, but it is not specifically used for making bricks.

Therefore, the correct answer is shale as it is commonly used in making bricks and cement.

The correct answer is sandstone
