Which environmental conditions can affect the performance of surface supplied diving systems?

The choice regarding water temperature, visibility, and currents accurately reflects the environmental conditions that significantly impact the performance of surface-supplied diving systems.

Water temperature is crucial because it can affect both diver comfort and the physiological responses of a diver's body. Cold water can lead to hypothermia, while excessively warm water can lead to overheating. Visibility is important for diver safety and operational efficiency; poor visibility can hinder navigation and increase the risk of accidents. Currents can affect the diver's ability to maneuver and may even pose a danger by sweeping the diver away from the intended work area or the surface support team.

Thus, understanding these specific conditions is vital for ensuring the safety and effectiveness of diving operations, making this option the best choice for this question.
