Assertion: Stressors can be external or internal in nature.

Reasoning: External stressors include environmental factors, while internal stressors can be psychological or emotional in nature.

Both Assertion and Reasoning are true, but the Reasoning is not the correct explanation of the Assertion.

The correct answer is Option 2: Both Assertion and Reasoning are true, but the Reasoning is not the correct explanation of the Assertion.

Assertion: Stressors can be external or internal in nature. This is correct. Stressors can indeed be both external (e.g., noise, crowding, natural disasters) and internal (e.g., worries, fears, anxiety).

Reasoning: External stressors include environmental factors, while internal stressors can be psychological or emotional in nature. This is also correct. External stressors come from the environment, such as temperature, pollution, or traffic. Internal stressors originate from within the person — often psychological or emotional, like self-doubt, guilt, or negative thinking.

The reasoning restates the classification, rather than explaining why stressors can be internal or external. It does not logically explain the assertion; it merely describes it. Hence, R does not explains A.
