  • Plants and seawater are receptors of $CO_2$
  • Micro organisms acts as both sink and source for dead plants and animals
  • Micro isocyanate is a pesticide and DDT is a contaminant.
  • $CO_2$ is not a pollutant. $CO_2$ is a gas that has played an enormous role in the development and sustainability of all life on this Earth.
Hence (a) is the correct answer.
