The correct answer is: d) All of the above

Livestock rearing plays an important role in Bihar’s rural economy, providing milk and meat, draught power, and manure for fertilizer.

• Milk and meat: Livestock, such as cows, buffaloes, goats, and sheep, are raised for their milk and meat. Milk is a nutritious food that is used to make a variety of products, such as cheese, yogurt, and butter. Meat is a good source of protein and other nutrients.
• Draught power: Bullocks and other animals are used as draught power to pull plows and carts. This helps farmers to cultivate their land and transport their produce.
• Manure for fertilizer: Animal manure is used as a fertilizer to improve the fertility of the soil. This helps to increase crop yields.

In addition to these benefits, livestock rearing also provides employment opportunities for people in rural areas. It also helps to improve the livelihoods of rural households by providing them with a source of income.
