The ‘Posa’ system practiced by some tribes involved:

Collection of tributes from neighboring villages
Ritual sacrifices
Communal land ownership
Elaborate festivals

The correct answer is: a) Collection of tributes from neighboring villages.

The Poșa system was a system of tribute collection practiced by some tribes in India. Under this system, the tribes would collect tributes from neighboring villages in exchange for protection. The tributes would often be in the form of food, livestock, or other goods.

The Poșa system was a way for the tribes to maintain their power and control over the surrounding area. It was also a way for them to obtain the resources they needed to survive.

The Poșa system was not without its critics. Some people argued that it was a form of extortion and that it was unfair to the neighboring villages. Others argued that it was a necessary evil, as it helped to keep the peace between the tribes and the neighboring villages.

The Poșa system eventually fell out of practice as the tribes came into contact with other cultures and adopted new ways of life. However, it remains a part of the history and culture of some of the tribes in India.
