Illegal mining is a concern in some parts of Punjab, leading to:

Revenue losses
Environmental degradation
Social conflicts
All of the above

The correct answer is: d) All of the above.

Illegal mining is a major concern in some parts of Punjab, leading to a number of problems, including revenue losses, environmental degradation, and social conflicts.

Revenue losses occur when the government does not collect taxes on the minerals that are extracted illegally. This can lead to a loss of revenue that could be used to fund important public services.

Environmental degradation occurs when mining operations are not conducted in a sustainable manner. This can lead to the destruction of forests, the pollution of water supplies, and the loss of biodiversity.

Social conflicts can arise when illegal mining operations displace people from their homes or damage their livelihoods. This can lead to tensions between local communities and mining companies, and in some cases, even violence.

In order to address the problem of illegal mining, it is important to strengthen the enforcement of mining laws and regulations. It is also important to raise awareness of the environmental and social impacts of illegal mining, and to provide alternative livelihoods for people who are displaced by mining operations.
