Final answer:

If you believe you're experiencing decompression sickness, you should immediately C. breathe 100% oxygen and contact emergency medical care.

Explanation:

In the event that you believe you're experiencing decompression sickness—also referred to as 'the bends'—it's important to respond immediately. The most correct option would be to breathe 100 percent oxygen and contact emergency medical care (option C). This is because decompression sickness can lead to serious health complications. It is not advisable to simply stop diving until you feel better or go back into the water. Nor should you wait until it is convenient to consult a doctor.

The use of oxygen-rich air (such as 100% O2) is recommended as it helps reduce the volume of inert gas bubbles in the body, alleviating symptoms and preventing further injury. Concurrently, seeking immediate emergency medical care is equally crucial, as professional health care providers can initiate recompression therapy, which is the definitive treatment for decompression sickness.
