The correct answer is:
D. Spills from oil tankers.
Explanation:
1. Oil pollution in the ocean mainly comes from oil tankers, which are large ships that transport oil across the seas.
2. When oil tankers experience accidents or malfunctions, they can release large amounts of oil into the ocean, causing significant pollution.
3. These oil spills can have devastating effects on marine life, ecosystems, and coastal communities.
4. While other sources like operating boats and personal watercraft, leaking underground storage facilities, and runoff from cities and towns can contribute to ocean pollution, oil tankers are often a major source of large-scale oil spills in the ocean.
