Which Statement Best Describes the Cause of Decompression Sickness

Which statement best describes the cause of decompression sickness?

A) Carbon dioxide bubbles come out of solution too quickly and burst blood vessels, especially in the brain.
B) Oxygen molecules are so tightly compressed due to pressure exerted by the water column that they cannot deliver oxygen to the tissues.
C) The oxygen molecule expands upon ascent and bursts, therefore causing a lack of oxygen to the tissues.
D) Carbon dioxide is driven into the cardiovascular system and causes acidosis.
E) Nitrogen gas bubbles form in the blood, joints, and nervous system as pressure decreases from too fast an ascent.
