Hello my friend
Explanation:
Reflex action is induced by the motor nerves. It is an involuntary and instant movement in response to a stimulus. A reflex action is done by neural pathway of reflex arc. In this, the action is done before the impulse reaches the brain. Out of the given options, sweating is not a reflex action. Salivation is a reflex action in which smell of food activate neural pathway and activates muscles and glands. This releases salivary juices. When someone is pinched by a needle, it activates neural pathway to evoke a response. The skin receptors quickly send nerve impulses to the spinal cord and response is relayed back. Apart from these, coughing, sneezing and blinking of eyes are also reflex actions.
Thus, the correct answer is 'Sweating.'
