Efforts to mitigate climate change in Bihar can involve:

The correct answer is: d) All of the above

Here is a brief explanation of each option:

• Promoting water conservation practices can help to reduce the amount of water that is used, which can in turn reduce the amount of greenhouse gases that are emitted. For example, people can be encouraged to take shorter showers, fix any leaks in their homes, and water their lawns less often.
• Planting trees to reduce soil erosion can help to prevent soil from being washed away by rain or wind. This can help to reduce the amount of sediment that is deposited in rivers and streams, which can in turn reduce the risk of flooding. Trees also absorb carbon dioxide from the atmosphere, which helps to mitigate climate change.
• Utilizing renewable energy sources can help to reduce the amount of reliance on fossil fuels, which are a major source of greenhouse gas emissions. Renewable energy sources include solar, wind, and hydropower.

All of these efforts can help to mitigate climate change in Bihar.
