The correct answer is: a) Hunter-gatherer
Mesolithic sites in Gujarat reflect a shift towards a hunter-gatherer lifestyle. This is evident from the archaeological evidence found at these sites, which includes tools and weapons used for hunting, as well as the remains of animals that were hunted. The shift to a hunter-gatherer lifestyle is likely due to the changing climate and environment of Gujarat during the Mesolithic period. The climate became drier and more arid, which made it difficult for people to live a settled agricultural lifestyle. As a result, people began to move around more frequently in search of food and water. This led to a more nomadic lifestyle, which is characterized by a lack of permanent settlements and a reliance on hunting and gathering for food.
The other options are incorrect for the following reasons:
- Option b) Agricultural is incorrect because there is no evidence that Mesolithic people in Gujarat were engaged in agriculture.
- Option c) Urban is incorrect because there were no cities or towns in Gujarat during the Mesolithic period.
- Option d) Nomadic is incorrect because Mesolithic people in Gujarat were not nomadic in the sense that they did not move around constantly. They did, however, move around more frequently than people who lived a settled agricultural lifestyle.
