Which of the following is a benefit of using a dry suit over a wetsuit?

Using a dry suit provides a significant advantage in terms of thermal insulation compared to a wetsuit. A dry suit is designed to keep water out completely, which means that the diver stays dry, while thermal insulation comes from the undergarments worn beneath the suit. These undergarments can be made from a variety of materials that trap body heat, allowing for effective insulation even in very cold water temperatures.

This capability to remain dry offers greater versatility in terms of temperature control, enabling divers to operate in colder environments without the risk of hypothermia that can be associated with wetsuits, which allow some water to enter and ultimately chill the body even as they provide some insulation. This makes dry suits particularly advantageous for prolonged dives in colder conditions, ensuring divers can maintain their core body temperature effectively.

While other options touch on aspects of suits, they do not offer the same level of thermal protection or insulation capability that a dry suit inherently provides.
