The correct answer is: d) All of the above

Rehabilitation of mined-out areas is important to restore the landscape, prevent erosion, and create livelihood opportunities.

• Restoring the landscape involves returning the mined-out area to a condition that is similar to its original state. This can be done by planting trees and other vegetation, and by restoring the soil.
• Preventing erosion is important to protect the environment and to ensure that the mined-out area is stable. Erosion can be prevented by planting trees and other vegetation, and by installing erosion control measures such as terraces and gabions.
• Creating livelihood opportunities is important to the local community and to the economy. Rehabilitation of mined-out areas can create jobs in the mining industry, as well as in the construction and tourism industries.

In addition to these three main reasons, rehabilitation of mined-out areas can also help to:

• Improve water quality by reducing runoff and sediment pollution
• Provide habitat for wildlife by creating wetlands and other natural areas
• Store carbon by planting trees and other vegetation

Overall, rehabilitation of mined-out areas is an important part of sustainable development. It can help to protect the environment, create jobs, and improve the quality of life for people in the local community.
