The correct statement is:

A. The signal travels through the nerve of the hand to the spinal cord and then to the brain.

When you touch a hot pot, sensory receptors in the skin of your hand detect the heat and send an electrical impulse through sensory nerves to the spinal cord. From there, the signal is relayed to the brain for processing, where you become aware of the pain.
