Solution

The correct option is D
Pseudomonas

Pseudomonas is gram-negative bacteria. It is used in the bioremediation of the oil-spills. The oil-spills refer to the accidental release of the oil from the ships and tankers in the water body. It causes great loss to the aquatic biodiversity and needs extensive efforts for cleanup. Bioremediation is the process of using bacteria and other microbes that are capable of breaking the organic pollutants. Pseudomonas is an aerobic bacteria that can utilise oil as an energy source, leading to the breakdown of oil. Hence, the correct answer is 'Pseudomonas'
