Detailed explanation-1: -It is the origination point of neural signals for voluntary muscle movement. Experiments in the 1930s by Foerster and Penfield demonstrated that electrical stimulation of the motor cortex could cause muscle contractions (see pages 110-112 for more).
Detailed explanation-2: -Answer-d. (d) Motor cortex is crucial for movement and bodily functions thereby stimulation of this part of the brain will cause movement of the lips and mouth.
Detailed explanation-3: -The Primary Motor Cortex: Upper Motor Neurons That Initiate Complex Voluntary Movements. The upper motor neurons in the cerebral cortex reside in several adjacent and highly interconnected areas in the frontal lobe, which together mediate the planning and initiation of complex temporal sequences of voluntary movements.
