The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states, "Life would have been impossible without green plants." - This implies that green plants play a crucial role in sustaining life on Earth. **Hint**: Consider the role of green plants in ecosystems and their contributions to life. 2. **Understanding the Reason**: - The reason states, "The food we consume and the oxygen we breathe are products of their activities." - This indicates that green plants are responsible for producing food (through photosynthesis) and oxygen (as a byproduct of photosynthesis). **Hint**: Think about the process of photosynthesis and its importance in the food chain and oxygen production. 3. **Evaluating the Truth of the Assertion**: - Green plants are essential for life as they produce oxygen and serve as the primary producers in ecosystems. - Therefore, the assertion is true. **Hint**: Reflect on the basic needs for life and how plants fulfill these needs. 4. **Evaluating the Truth of the Reason**: - Since green plants produce food and oxygen, the reason is also true. - Photosynthesis is the process through which plants convert sunlight into chemical energy, producing glucose and oxygen. **Hint**: Consider how the food chain starts with plants and how oxygen is vital for respiration. 5. **Determining the Relationship Between Assertion and Reason**: - The reason explains why the assertion is true. Without green plants, we would not have the food and oxygen necessary for life. - Thus, the reason is the correct explanation for the assertion. **Hint**: Analyze how the reason supports the assertion logically. 6. **Conclusion**: - Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. - Therefore, the correct answer is: **Option A** - Both assertion and reason are true, and reason is the correct explanation of assertion. ### Final Answer: **Option A** - Both assertion and reason are true, and reason is the correct explanation of assertion.
