C. Swimming in the open sea

Option (A)

Explanation:

The ocean covers the larger water bodies on earth. The larger ships in the oceans are continuously releasing waste materials such as sewage, leakage of oil and other solid waste products. In addition to this, oil spills also occur and it releases the petroleum hydrocarbons into the ocean and polluting the water. These waste products contain various types of harmful chemicals that can reduce the amount of oxygen present in the ocean water for the survival of the marine organisms. Due to this release of waste materials into the oceans, the marine species are highly affected, thereby creating de-stability in the ocean environment.

Thus, the correct answer is option (A).

Your answer is A. Dumping waste from ships.
