Which of the following is a common safety practice while wreck diving?

Maintaining a buddy system is a fundamental safety practice in wreck diving, as it enhances safety and communication. When divers explore wrecks, which may present unique hazards such as entanglement, poor visibility, or challenging exit routes, having a buddy ensures that help is readily available in case of an emergency. This practice allows divers to monitor each other's air supply, assist with navigation, and respond quickly to any potential issues.

The buddy system also helps divers maintain situational awareness, as they can share observations and decisions while managing the complexities that wreck environments often present. Furthermore, having a companion increases overall safety, especially in the event of becoming disoriented or facing any unforeseen difficulties during the dive.
