Drop by drop—that is how most oil enters the oceans. Catastrophic spills make the headlines, but it is the chronic dribble, dribble, dribble of seemingly small inputs that supplies most of the oil polluting the world’s oceans.- Oceanus magazine

So is it b.?

c

THANK YOU VERY MUCH DUDE!!!!!!!!!!!!!!!!! :')

You're welcome! I'm glad I could help clarify things for you. In this case, the correct answer is actually c. Runoff from cities and towns. Although leaks from underground storage facilities and spills from oil tankers do contribute to oil pollution in the oceans, most of the oil that pollutes the ocean actually comes from the everyday activities of people on land.

Cities and towns produce runoff through activities such as road construction, car maintenance, and improper disposal of oil and other petroleum products. When it rains, this runoff carries oil and other pollutants into rivers and ultimately into the ocean. This chronic dribble of oil inputs from various sources accumulates over time and causes significant harm to marine ecosystems.

It's important to be aware of our actions on land and take steps to minimize pollution, such as properly disposing of oil and other hazardous materials and using eco-friendly alternatives.
