The Gate-control theory can explain this method of reducing pain. Option C is the correct answer.
According to the "gate control" theory, the spinal cord has a neurological "gate" that either shuts off or permits pain signals to reach the brain. This hypothesis is frequently used to explain problems with phantom and persistent pain.
The spinal cord's gate distinguishes between different fiber types when sending pain signals, in contrast to a real gate, which opens and closes to let everything pass through. In particular, impulses from large nerve fibers are inhibited whereas signals from tiny nerve fibers are allowed to pass.
