Why are divers advised not to come up suddenly?
Answer and explanation
Correct answer: Dissolved gas may form bubbles rapidly and cause problems
At depth, high pressure allows more nitrogen and other gases to dissolve in body fluids. During a rapid ascent, pressure falls quickly, so the dissolved gas can come out of solution as bubbles. These bubbles may damage tissues and block circulation. Slow ascent and decompression stops reduce this risk; the other choices describe no such mechanism.
