Answer 1

Hint: In this oil spill, where a natural resource and specifically pollution was used as a strategy of war for the first time in military history. Though it is hard to know the full scale of the spill for certain, many scientists believe it to be one of the worst in human history.

Complete answer:
To answer this question, first, we need to know about the oil spill. Oil spill is the discharge of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.
Now, let us find the solution from the option.
The world’s largest oil spill was not an accident. It occurred because of a war. During the Gulf war in 1991, as the Iraqi forces left Kuwait, they released pipelines and the valves of oil wells and set the fire as to stop the forces of the United States from landing in the area.
The fire initiated after the releasing of the first well in January 1991 had continued until the capping of the last well in April month of that year. As a result, nearly 240 million gallons of oil are expected to have been released into the Persian Gulf, killing hundreds of fishes and marine mammals.

Thus, the correct option is D. i.e. February 1991 in Persian Gulf.

Note:Oil spill disasters have been one of the main concerns of the marine ecosystem for a long period now which are commercial and environmental catastrophes. As a result of an accidental situation including oil rigs or ships, the ocean water bodies get polluted by liquid petroleum hydrocarbons, affecting harm to the marine ecosystem for eras to come.
