Activities that may increase the risk of decompression sickness include:

Relaxing during the dive.
Training and experience.
Maintaining proper buoyancy.
Diving with a buddy.

The correct answer is: Training and experience.

In the context of scuba diving, decompression sickness occurs when a diver ascends too quickly from depths, causing nitrogen bubbles to form in the body. While training and experience are crucial for safe diving, they can also inadvertently lead to increased risk if divers push their limits or do not fully adhere to safe diving practices. A highly experienced diver may feel confident enough to ignore some safety protocols, which could include ascending too quickly or diving beyond recommended limits. This scenario emphasizes that even seasoned divers must remain vigilant about following established diving safety guidelines to avoid potential risks, including decompression sickness. Maintaining proper buoyancy, relaxing during the dive, and diving with a buddy are generally associated with safer diving practices and help mitigate the risk of decompression illness by promoting stable ascent rates and reducing the chances of erratic movements underwater.
