Question

What is the depth threshold where most scuba divers generally begin to be affected by nitrogen narcosis.

a. Around 100 feet (30 meters).
b. Around 30 feet (9 meters).
c. Around 200 feet (61 meters).
d. Around 10 feet (3 meters).

Answer 1

Most scuba divers begin to be affected by nitrogen narcosis around 100 feet (30 meters), experiencing various symptoms due to the narcotic effect of nitrogen.

Step-by-step explanation:

The depth threshold where most scuba divers generally begin to be affected by nitrogen narcosis is around 100 feet (30 meters). At this depth, divers can experience a variety of symptoms caused by the narcotic effect of nitrogen under high pressure. The severity of the symptoms generally increases with depth, which is why divers must be cautious and well-trained to handle the effects of increased pressures underwater.
