Correct Answer: Recycling

Solution : The correct answer is (B) Recycling

The process of converting waste materials into reusable materials is called recycling. Recycling involves collecting and processing waste materials such as paper, plastics, glass, metals, and organic matter, and transforming them into new products or raw materials that can be used again.

Recycling helps reduce the consumption of finite resources, minimize the need for raw material extraction, and decrease the amount of waste sent to landfills or incineration. It contributes to the conservation of energy, water, and natural resources, as well as the reduction of pollution and greenhouse gas emissions associated with the production of new materials.

Through recycling, waste materials are sorted, cleaned, and processed to remove impurities and contaminants. They are then transformed into new products through various methods such as melting, shredding, crushing, or chemical processes. These recycled materials can be used in the manufacturing of new products, reducing the demand for virgin materials and the environmental impact of resource extraction.
