Solution

The correct option is B The pressure inside our body is equal to the atmospheric pressure.
The pressure exerted by the atmosphere near the Earth's surface is called atmospheric pressure. Inside the body, the flowing blood and body fluids create a pressure which counters the effect of atmospheric pressure. We are not crushed because the atmospheric pressure is balanced by the pressure inside our body.
