The correct answer is A) Bullocks.
Bullock carts are a common sight in rural Telangana, where they are used for transportation and agricultural work. Bullocks are strong and sturdy animals that are well-suited to the hot and dry climate of the region. They are also relatively inexpensive to maintain, making them a popular choice for farmers and other rural residents.
Horses are also used in Telangana, but they are more expensive than bullocks and require more care. Camels are found in some parts of the state, but they are not as common as bullocks or horses. Mules are not native to Telangana, and they are not used in the state.
In conclusion, the most important livestock animal for rural transportation and agricultural work in Telangana is the bullock.
