The correct answer is: C) Reddys.
The Reddys were a Telugu-speaking Hindu warrior caste that held significant landholdings in some feudatory states in the Deccan region of India. They were originally a pastoral people who migrated to the Deccan from the north in the 12th century. They quickly rose to prominence and became one of the most powerful castes in the region. The Reddys played a major role in the Vijayanagara Empire, which was one of the largest and most powerful empires in South Asia. They were also involved in the Mughal Empire and the Maratha Empire. The Reddys continue to be a powerful caste in the Deccan region today.
The other options are incorrect for the following reasons:
- Option A: Brahmins are a Hindu caste that is traditionally associated with the priesthood. They were not a major landholding caste in the Deccan region.
- Option B: Muslims are a religious group that originated in the Middle East. They did not hold significant landholdings in the Deccan region.
- Option D: Tribal groups are indigenous peoples who live in rural areas. They did not hold significant landholdings in the Deccan region.
