Recently, "oilzapper" was in the news. What is it?

1. Oilzapper is an eco-friendly technology developed in India by TERI (The Energy and Resources Institute) for the bioremediation of environments contaminated with crude oil. 2. It involves using a consortium of five different bacterial strains that feed on hydrocarbon compounds present in oily sludge and oil spills, converting them into harmless CO2 and water. 3. Option (A) correctly describes this: It is an eco-friendly technology for the remediation of oily sludge and oil spills. 4. Option (B) is incorrect; Oilzapper is for cleaning up spills, not for under sea oil exploration. 5. Option (C) is incorrect; Oilzapper is a microbial product, not a genetically engineered maize variety for biofuel. 6. Option (D) is incorrect; it is used for bioremediation, not for controlling flames from oil wells.
