  • B
    Increasing deforestation, slowing down the growth of human population.
  • C
    Increasing deforestation, reducing efficiency of energy usage.
  • ✓

Answer

Correct option: D.
Reducing deforestation, cutting down use of fossil fuel.
Global warming is the biggest challenge for the developing countries like India. The rapid increase in human population and the increased levels of pollution are the major contributors of global warming.
The percentage of heat$-$trapping carbon dioxide $(\mathrm{CO}_2)$ increases due to the burning of fossil fuels to generate electricity, fuel our cars, and heat our homes.
Deforestation also increases the concentration of carbon dioxide in the atmosphere.
