Answer 1

The correct option is A (ii) and (iii)

Reflex action is an action provided in response to a stimulus from the environment. It is an immediate action taken without much thinking and it does not have our control. The spinal cord is responsible for the response of the body because the impulse has not reached the brain till then. Therefore, the correct answer is option A.
