The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states, "Matter can neither be created nor be destroyed." - This statement is a reflection of the **Law of Conservation of Mass**, which asserts that in a closed system, the total mass remains constant over time, regardless of the processes acting inside the system. This means that matter can change forms (e.g., from solid to liquid) but cannot be created or annihilated. 2. **Understanding the Reason**: - The reason states, "This is the law of definite proportions." - The **Law of Definite Proportions** (also known as Proust's Law) states that a chemical compound will always contain its constituent elements in a fixed ratio by mass, regardless of the amount of the compound or how it was prepared. For example, water (H2O) always consists of 2 hydrogen atoms and 1 oxygen atom. 3. **Evaluating the Truth of Each Statement**: - The assertion is true because it correctly describes the Law of Conservation of Mass. - The reason is false because it incorrectly identifies the assertion as the Law of Definite Proportions instead of the Law of Conservation of Mass. 4. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is true but the reason is false. ### Final Answer: - The correct option is: **Assertion is true, but Reason is false.** ---
