Because , we make al things from petroleum like
diesel and petrol that's why the option A is correct.

Answer:

Introduction:
The treasure from the earth that provides us with petrol, diesel, coal tar, kerosene, wax, and many other valuable products is called petroleum. Petroleum is a naturally occurring fossil fuel that is formed from the remains of ancient plants and animals buried deep within the Earth's crust over millions of years. It is a vital resource that plays a significant role in our daily lives.

Petroleum:
Petroleum, also known as crude oil, is a complex mixture of hydrocarbons, which are organic compounds consisting of hydrogen and carbon atoms. It is found in underground reservoirs or oil wells. Petroleum is a non-renewable resource, meaning it takes millions of years to form and cannot be easily replenished.

Extraction and Refining:
The extraction of petroleum involves drilling deep into the Earth's surface to reach the oil reservoirs. Once the oil is extracted, it undergoes a refining process to separate it into different components based on their boiling points. This process is known as fractional distillation.

Products derived from Petroleum:
Petroleum is a versatile resource that provides us with various valuable products. Here are some of the essential products derived from petroleum:

1. Petrol (Gasoline): It is a fuel used in automobiles and other internal combustion engines.

2. Diesel: Diesel fuel is used in diesel engines, such as those found in trucks, buses, and some cars.

3. Kerosene: Kerosene is a type of fuel used for heating, cooking, and aviation purposes.

4. Coal Tar: Coal tar is a thick, black liquid obtained during the production of coke or coal gas. It is used in the manufacturing of various products, including road surfacing materials, roofing materials, and dyes.

5. Wax: Petroleum wax is derived from the residue left after the distillation process. It is used in the production of candles, polishes, and coatings.

6. Lubricants: Petroleum is also used to produce lubricants, such as motor oil, which reduce friction and wear between moving parts.

7. Petrochemicals: Petrochemicals are chemical compounds derived from petroleum. They are used in the production of plastics, synthetic fibers, detergents, fertilizers, and many other products.

Conclusion:
Petroleum is a valuable treasure from the Earth that provides us with essential fuels, lubricants, and various other products. It is a finite resource that requires careful management and conservation to ensure its availability for future generations.
