Detailed explanation-1: -Thus, reflex arc transmits the information from receptor to effector via the spinal cord. The brain is not the part of the reflex arc. Thus, option D is the correct answer.
Detailed explanation-2: -Sweating is not a reflex action. It is primarily a means of temperature regulation. But, salivation on seeing food, hand withdrawal because of the needle and blinking of the eyes due to bright light are all examples of reflex actions.
Detailed explanation-3: -A reflex arc is a connection between perceiving the signal from the nerves and promptly responding to it. In a reflex action, the brain plays no part. The spinal cord, which reacts without thinking about how to respond to stimuli, is in charge of these automatic actions.
