The early inhabitants of Kerala likely practiced a form of:

Feudalism
Nomadism
Hunter-gatherer lifestyle
Advanced agriculture

The correct answer is: C) Hunter-gatherer lifestyle

The early inhabitants of Kerala were hunter-gatherers. They lived in small groups and moved from place to place in search of food. They hunted animals, gathered fruits and vegetables, and fished. They did not have permanent homes and lived in temporary shelters.

Feudalism is a system of government in which land is owned by a small number of people, called lords, who rent it out to peasants in exchange for labor and loyalty. Nomadism is a lifestyle in which people move from place to place, often following herds of animals. Advanced agriculture is a system of farming that uses modern techniques and technology to produce large amounts of food.

The early inhabitants of Kerala did not practice feudalism, nomadism, or advanced agriculture. They were hunter-gatherers who lived in small groups and moved from place to place in search of food.
