If a student says all quick responses occur after thinking in the brain, which example disproves it?

Answer and explanation

Correct answer: गर्म वस्तु छूते ही हाथ हटना

The governing concept is reflex action. When the hand touches a hot object, sensory receptors send an impulse through a reflex arc, and the spinal cord rapidly coordinates the withdrawal before conscious thinking by the brain. Therefore, option A disproves the statement. Memorising, deliberate thinking, and drawing generally involve conscious brain activity, so they are not suitable counterexamples.
