Which of the Following Is True About the Physiological Effect

Which of the following is true about the physiological effect of water on nerve conduction velocity?

A) Increased nerve conduction velocity is proportional to hydrostatic pressure.
B) The effect depends primarily on the temperature of the water.
C) There is a decrease in nerve conduction velocity for body parts immersed in water.
D) Nerve conduction velocity adjusts upon entering the water, resulting in a generalized relaxation response.
