The correct Answer is:
To solve the question regarding the two statements about Plexiglas and PMMA, we will analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1:** Plexiglas is the commercial name of PMMA. - PMMA stands for polymethyl methacrylate, which is a synthetic polymer. - Plexiglas is indeed a well-known commercial name for PMMA, along with other names such as acrylic glass and perspex. **Conclusion for Step 1:** This statement is **true**. ### Step 2: Analyze Statement 2 **Statement 2:** It is used in making contact lenses because it has excellent light transmission property. - PMMA has a high light transmission rate, allowing it to transmit up to 92% of visible light. - This property makes PMMA suitable for optical applications, including contact lenses. - Additionally, PMMA is lightweight and durable, which are essential characteristics for contact lenses. **Conclusion for Step 2:** This statement is also **true**. ### Step 3: Determine the Relationship Between the Statements - Since both statements are true and the second statement provides a reason for the first statement, we can conclude that Statement 2 is a correct explanation of Statement 1. ### Final Conclusion Both statements are true, and Statement 2 correctly explains Statement 1. Therefore, the answer is **Option A**: Both statements are true, and Statement 2 is the correct explanation of Statement 1. ---
