Which is an indication that a man might be choking

The answer is C, he loses consciousness. It is because they had not been getting enough air and passed out.

He loses consciousness.

Explanation:

Choking occurs when the trachea is blocked by liquids, food or any kind of object. The epiglottis, a kind of laryngeal port, moves as needed. The epiglottis is open for air to pass into the lungs, but when we swallow something, the epiglottis closes to prevent food from entering the wrong channel.

Thus, when the epiglottis fails for any reason, food or fluid is lost and travels through the larynx preventing air from reaching the lungs. When this occurs, the body releases air jets to expel such food.

If you happen to have purplish skin, it is a sign that choking is blocking air, which may cause you to have a respiratory arrest, loss of consciousness, a faint or more serious situations.
