Correct Answer: A
Solution :
Reflex action is an immediate involuntary response to a stimulus. The reflexes developed by training and learning are called conditioned or acquired reflexes. During learning, these activities occur under cerebral control, but once established these occur by habit as reflexes. Some common examples are, dancing, cycling, playing, driving, etc. In the reflex actions, a sensory impulse reaching central nervous system (brain or spinal cord) is itself returned to an effector as a motor impulse without neuronal analysis and integration. Naturally the necessary response automatically and suddenly occurs almost as soon as a stimulus is received. The common examples are, sudden with drawl of hands or feet, with a jerk, from sudden contact with hot or cold or sharp object etc.
