Best answer
Right choice is (c) Heavy metals

The explanation is: Heavy metals definitely can affect the microbial population in the habitat as they have the potential to degrade the organisms present in the environment. As metal polluted sites are contaminated and hence harmful to the environment. Green algae, Kitchen waste and oxygen are the compounds that are not harmful to the microbial population or the environment.
