Question

which example best describes a reflex action?
a. going for a walk outside
b. eating food when hungry
c. coughing when the throat is irritated
d. bending down to lift a heavy object

Explanation:

A reflex action is an involuntary, automatic response to a stimulus. Let's analyze each option:

• Option A: Going for a walk outside is a voluntary action, not a reflex.
• Option B: Eating food when hungry is a voluntary, goal - directed action based on the need for sustenance, not a reflex.
• Option C: Coughing when the throat is irritated is an involuntary response to a stimulus (throat irritation), which fits the definition of a reflex action.
• Option D: Bending down to lift a heavy object is a voluntary action that we decide to do, not a reflex.

Answer:

C. coughing when the throat is irritated
