Answer:
A. Nervous and muscular
Explanation:
The thermoreceptors of the sensory afferent pathway were activated when they perceived high temperatures, and after that they sent a signal to the CNS for it to execute the "withdrawal" reflex in the face of danger or pain.
The reflex act is an immediate and unconscious action, like walking, and like other movements that are coordinated between the CNS, SNP, NEUROMUSCULAR PLATE AND MUSCLE.
