The correct answer is: (c) Goats and Sheep.
Goats and sheep are the most common type of livestock reared in the hilly regions of Assam. They are hardy animals that can thrive in the mountainous terrain and climate. Goats are particularly well-suited to the region, as they are able to climb steep slopes and browse on tough vegetation. Sheep are also raised in Assam, but they are not as common as goats.
Cattle and buffaloes are also reared in Assam, but they are not as common as goats and sheep. Cattle are more suited to the plains of Assam, while buffaloes are more suited to the wetlands. Pigs are not commonly reared in Assam, as they are not well-suited to the climate and terrain.
Goats and sheep are raised for their meat, milk, and wool. Goat meat is a popular dish in Assam, and sheep’s milk is used to make cheese and other dairy products. Wool is used to make clothing and other textiles.
Goats and sheep are also raised for their manure, which is used as fertilizer. Manure is an important source of nutrients for crops, and it helps to improve soil quality.
Goats and sheep are an important part of the economy of Assam. They provide food, clothing, and other products for the people of Assam, and they also help to improve the environment.
