The most common livestock raised in Mizoram are:

Cows and buffaloes
Pigs and poultry
Sheep and goats
Camels and yaks

The correct answer is: a) Cows and buffaloes.

Mizoram is a state in northeastern India. It is bordered by Assam to the north, Tripura to the south, Bangladesh to the west, and Myanmar to the east. The state has a population of over 1.1 million people, of which the majority are ethnic Mizos.

The main occupation of the people of Mizoram is agriculture. The main crops grown are rice, maize, and sugarcane. Livestock is also an important part of the economy, with the main animals raised being cows, buffaloes, pigs, and poultry.

Cows and buffaloes are the most common livestock raised in Mizoram. They are used for their milk, meat, and labor. Pigs are also raised for their meat, and poultry is raised for their eggs and meat.

Sheep and goats are not as common as cows, buffaloes, pigs, and poultry. They are raised for their meat and wool. Camels and yaks are not raised in Mizoram. They are found in the Himalayan region.

I hope this helps!
