That sure is a garbage question. The best answer is clearly A. Even though I get it, most of the people squirting blood out of their ears and nose at the surface ran out of air and held their breath.

Also, people panicking and about to drown, usually are nearly silent, and hardly splash at all. A good life guard can spot it, the average diver? Forget about it. It’s rare to hear "help".
