Answer:

I'm pretty sure it's C. Since his heart beat is barley audible and is blood pressure is barley obtainable.

Explanation:

Cardiac tamponade puts pressure on the heart and keeps it from filling properly. The result is a dramatic drop in blood pressure that can be fatal.

Symptoms include low blood pressure, shortness of breath, and lightheadedness.

Emergency treatment is required. Usually, a needle or small tube is used to drain excess fluid.
