The correct Answer is:
To analyze the assertion and reason provided in the question, we can break down the information step by step. ### Step 1: Understand the Assertion The assertion states that during physical exercise, the functions of various organs such as muscles, lungs, heart, blood vessels, and kidneys are coordinated. This means that these organs work together to support the increased physical demands placed on the body during exercise. **Hint:** Think about how different organs contribute to physical activity. What happens to your breathing, heart rate, and muscle activity when you exercise? ### Step 2: Understand the Reason The reason explains that the coordination of these organs is managed by both the neural system and the endocrine system. The neural system sends signals to different organs to adjust their functions, while the endocrine system releases hormones that also help regulate these functions. **Hint:** Consider how your body responds to stress or physical activity. What systems are involved in sending signals and regulating functions? ### Step 3: Connect the Assertion and Reason Both the assertion and the reason are true. The assertion correctly describes the coordination of organ functions during exercise, and the reason accurately explains how this coordination is achieved through the neural and endocrine systems. **Hint:** Reflect on the relationship between the assertion and reason. Does the reason provide a valid explanation for the assertion? ### Step 4: Determine the Correct Option Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, the conclusion is that both statements are correct. **Hint:** Look for options that indicate both statements are true and that the reason explains the assertion. ### Final Conclusion Both the assertion and the reason are true, and the reason is the correct explanation for the assertion. ### Summary of Steps: 1. Analyze the assertion about organ coordination during exercise. 2. Understand the role of the neural and endocrine systems in this coordination. 3. Connect the assertion and reason to see if they support each other. 4. Determine that both statements are true and that the reason explains the assertion.
