The CO2 concentration can be reduced by:

a. Alternative energy sources: Using renewable energy sources like solar, wind, and hydroelectric power can significantly reduce CO2 emissions. These sources do not burn fossil fuels to generate electricity, thus they do not release CO2.

b. Increasing energy consumption: This option is incorrect. Increasing energy consumption typically leads to higher CO2 emissions, especially if the energy is produced from fossil fuels.

c. Improved efficiency: By improving energy efficiency, we can get the same output from less energy input. This means burning fewer fossil fuels and releasing less CO2. This can be achieved in many ways, such as using energy-efficient appliances or improving insulation in buildings to reduce heating and cooling needs.

d. Fossil fuel
