The chemical responsible for the grey color of cement is Iron oxide (option D).

Explanation:
Cement is a widely used construction material that is known for its grey color. The grey color of cement is primarily due to the presence of iron oxide.

Iron oxide:
- Iron oxide, also known as ferric oxide or rust, is a chemical compound composed of iron and oxygen. It occurs naturally in various forms and is commonly found in rocks, soils, and minerals.
- When iron oxide is present in cement, it imparts a grey color to the final product.

Role of iron oxide in cement:
- Iron oxide is added to cement during the manufacturing process as a coloring agent.
- The amount of iron oxide added can vary depending on the desired color of the cement.
- The presence of iron oxide also contributes to the strength and durability of the cement.

Other components of cement:
- Cement is primarily composed of calcium, silicon, aluminum, and iron.
- The main chemical components of cement are calcium oxide (CaO), silicon dioxide (SiO2), aluminum oxide (Al2O3), and iron oxide (Fe2O3).
- These components react together during the manufacturing process to form a solid, strong material known as cement.

Conclusion:
In conclusion, the chemical responsible for the grey color of cement is iron oxide. Iron oxide is added to cement as a coloring agent and contributes to the strength and durability of the final product.
