The correct answer is B. Ghee: Milk.
In the other three pairs, the first word is a product that is obtained from the second word. Metal is obtained from ore, gasoline is obtained from petroleum, and soil is obtained from the earth. Ghee, on the other hand, is not obtained from milk. It is made from milk by heating it and then skimming off the fat.
Here is a more detailed explanation of each pair:
Metal: Ore
Metals are naturally occurring elements that are found in ores. Ores are rocks or minerals that contain a high concentration of a metal. To extract the metal from the ore, it must be mined and then processed. The processing methods vary depending on the type of metal and the type of ore.Gasoline: Petroleum
Petroleum is a naturally occurring liquid that is found in underground reservoirs. It is a mixture of hydrocarbons, which are compounds that are made up of hydrogen and carbon atoms. Petroleum is a valuable resource because it can be refined into gasoline, diesel fuel, and other products that are used in transportation.Soil: Earth
Soil is the loose material that covers the surface of the earth. It is made up of a mixture of minerals, organic matter, water, and air. Soil is essential for life because it provides plants with the nutrients they need to grow.Ghee: Milk
Ghee is a type of clarified butter that is made from milk. It is made by heating milk until the water evaporates and the fat separates from the milk solids. Ghee is a popular cooking oil in India and other parts of the world. It is also used in religious ceremonies and as a medicine.
