Explanation

Oilzapper is a bio remediation technique developed by The Energy and Resources Institute in India. It consists of a cocktail of five different bacterial strains that feed on the hydrocarbon compounds present in crude oil and oily sludge. These bacteria convert the hazardous oil contaminants into harmless carbon dioxide and water. This technology is considered eco friendly because it uses biological agents to clean up environmental pollutants without the use of harsh chemicals. It is widely used to treat oil spills on land and manage the oily waste generated by refineries. Therefore, option A is the correct description.
