Which of the following is a key reason for monitoring dive time?

Monitoring dive time is crucial for adhering to no-decompression limits, which are the maximum times divers can spend at certain depths without needing to perform decompression stops during their ascent. Staying within these limits helps prevent decompression sickness, often known as "the bends," which can occur when nitrogen absorbed by the body while diving forms bubbles during a rapid ascent to the surface. By tracking dive time effectively, divers ensure they remain within safe parameters, allowing for a safe return to the surface without the need for additional decompression stops. This practice is essential for maintaining diver safety and health during underwater excursions.

While ensuring an enjoyable experience, calculating oxygen consumption, and keeping track of underwater wildlife can be important considerations in the overall diving experience, they do not directly relate to the critical factor of safety associated with no-decompression limits.
