Right option is (d) Bacillus cereus

The explanation: Bacillus cereus is a bacterium which is known to degrade DDT insecticide but it is not a fungus, whereas, Aspergillus niger, Mucor alternans, Penicillium sp. are the fungi that are known to degrade DDT insecticide. As the microorganisms are used to degrade xenobiotic compounds, it is the best method. It can degrade all the pollutants efficiently and don’t cause any harm to the environment.
