The correct option is (d) Glass

The explanation is: Glass contamination of the soil doesn’t lead to reduction in bacteria in the soil or any other microorganisms like fungi and actinomycetes. Copper, cadmium, mercury and zinc etc. are found in the soil which when contaminated leads to variable reduction in bacteria, fungi and actinomycetes in the soil.
