What is the correct response to a four-line pull from the tender to the diver?

• A. Come up.
• B. Haul me up.
• C. Lower or Give me slack.
• D. I am all right.

Answer: (A)

When a four-line pull is made by the tender, it is the signal for the diver to ascend. The best response from the diver is “Come up,” which confirms acknowledgment of the ascent instruction and initiates a controlled rise toward the surface with the line guiding the ascent. This keeps communication clear and ensures the tender can haul the line as the diver ascends. Saying “Haul me up” might feel like a request rather than acknowledging the surface signal, while “Lower or Give me slack” or “I am all right” would not align with the intended action of rising to the surface.
