Question 1

Following a significant crude oil spill impacting the coastal mangroves and backwaters of Kerala, local authorities are exploring advanced remediation strategies. Which biotechnological approach offers the most sustainable and environmentally sound solution for long-term cleanup in this sensitive ecosystem?

Accepted Answer

B. Introduction of genetically modified bacteria specifically engineered to metabolize and detoxify petroleum hydrocarbons. — The correct answer is B. Introducing genetically modified bacteria for bioremediation is a biotechnological approach that utilizes microorganisms' metabolic pathways to break down pollutants into less harmful substances. This method is sustainable and environmentally sound as it naturally degrades the hydrocarbons, unlike chemical dispersants (A) which can be toxic or physical removal methods like dredging (C) and high-pressure washing (D) that are disruptive and may not fully eliminate the pollutant from the ecosystem.

Answer

A. Extensive application of synthetic chemical dispersants to break down the oil into smaller droplets.
