The correct answer is: d) All of the above

Conflicts over natural resources can arise between different communities within Assam, Assam and neighboring states, and industries and environmentalists.

• Conflicts between different communities within Assam can arise due to competition for scarce resources, such as land, water, and forest products. These conflicts can be exacerbated by ethnic and religious differences, as well as by historical grievances.
• Conflicts between Assam and neighboring states can arise due to disputes over the sharing of water resources, such as the Brahmaputra River. These conflicts can also be exacerbated by border disputes and by competition for economic resources.
• Conflicts between industries and environmentalists can arise over the development of natural resources, such as mining and oil and gas exploration. These conflicts can be due to concerns about the environmental impact of these activities, as well as about the distribution of the benefits and costs of development.

These are just some of the ways in which conflicts over natural resources can arise in Assam. It is important to understand the root causes of these conflicts in order to find sustainable solutions.
