The correct Answer is:
To analyze the given statements, we will evaluate each statement step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Vulcanization introduces S-S crosslinking in rubber. - **Explanation:** Vulcanization is a chemical process that involves heating natural rubber with sulfur. This process creates cross-links between the rubber polymer chains, specifically through sulfur-sulfur (S-S) bonds. The introduction of these cross-links enhances the strength, elasticity, and durability of the rubber. Therefore, Statement 1 is **True**. ### Step 2: Evaluate Statement 2 **Statement 2:** Vulcanized rubber has low water absorption tendency. - **Explanation:** The vulcanization process not only strengthens rubber but also alters its physical properties, including its interaction with water. Vulcanized rubber tends to have a lower water absorption tendency compared to unvulcanized (natural) rubber. This is because the cross-linking reduces the number of free spaces within the rubber structure that can hold water. Therefore, Statement 2 is also **True**. ### Step 3: Determine the Relationship Between the Statements - Since both statements are true, we need to check if Statement 2 provides a correct explanation for Statement 1. The reduction in water absorption due to vulcanization is a direct consequence of the cross-linking introduced in Statement 1. Thus, Statement 2 can be considered a correct explanation of Statement 1. ### Conclusion Both statements are true, and Statement 2 correctly explains Statement 1. Therefore, the correct answer is that both statements are true, and Statement 2 is a correct explanation of Statement 1. ### Final Answer **Both statements are true, and Statement 2 is a correct explanation of Statement 1.** ---
