1. **Identify the definition of a reflex:** A reflex is an automatic, involuntary response to a stimulus that does not require conscious thought. 2. **Analyze each option:** - **Option 1:** *A man salivates while watching a chef fry sausages.* Salivation is an automatic physiological response that can be triggered by sensory cues, such as the aroma or sight of food. This aligns with the definition of a reflex. - **Option 2:** *A woman puts her coat on before stepping out into the cold.* This is a voluntary, conscious behavior rather than an automatic response. - **Option 3:** *A child runs out to watch a fire engine drive by.* Although the action may be a quick response, it involves a conscious decision and is not considered a reflex. - **Option 4:** *A child drinks water after eating spicy food.* Drinking water here is a deliberate action taken to alleviate discomfort, not an involuntary reflex. 3. **Determine the best exemplification of a reflex:** Since a reflex is an involuntary response, the option that best fits this definition is the one involving the man salivating, as it is an automatic physiological reaction. 4. **Final Answer:** The option that best exemplifies a reflex is: **A man salivates while watching a chef fry sausages.**
