Answer :
The importance of agriculture lies in the fact that it serves as a vital source of raw materials. This means that agricultural activities provide the necessary resources for various industries and sectors. Agriculture plays a crucial role in producing food, fiber, and other materials essential for human consumption and industrial processes.
By cultivating crops and raising livestock, agriculture ensures a steady supply of food for the population. Additionally, agricultural products like cotton, timber, and medicinal plants are used in various industries for manufacturing goods.
Therefore, agriculture is not about increasing crime, polluting the environment, or increasing the number of orphans. Instead, it is a key sector that supports the economy, provides employment opportunities, and sustains livelihoods around the world.
In conclusion, the correct option that is NOT a rural area is C. A source of raw materials, as agriculture is crucial for providing these raw materials.
