Air as a diver comes up from depth due to pressure
A) compresses
B) expands
C) pressurizes
D) depresses

B) Expands

Explanation:

When the diver surfaces- one of the most important rules is to be continuously breathing. Never hold your breath when ascending. This is due to the air in the lungs will start to expand because there is less pressure of the water exerted on the body. Holding your breath can cause catastrophic injury to divers lungs.

D) depresses

Explanation:

When you dive, the water builds pressure and the the antonym (opposite) of pressurize is depressurize. Therefore, the water pressure depresses.
