Phantom limbs are a phenomenon in which individuals perceive sensation or movement in a limb that has been amputated. Modern methods have shown that this occurs because the somatosensory cortex, the area of the brain responsible for processing sensory information from the body, reorganizes and becomes responsive to alternative inputs after the amputation. This leads to the sensation of a phantom limb, as the brain continues to receive signals from the area that used to correspond to the limb even though it is no longer there. Therefore, option A is the best choice. The other options are not directly involved in the development of phantom limbs.
