The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Terms**: - First, we need to define what crystalline and amorphous solids are. Crystalline solids have a well-defined, ordered arrangement of atoms, while amorphous solids have a random arrangement of atoms. 2. **Analyzing the Assertion**: - The assertion states that "Quartz glass is a crystalline solid and quartz is an amorphous solid." - This is incorrect because quartz glass is actually an amorphous solid, and quartz (the mineral) is a crystalline solid. 3. **Analyzing the Reason**: - The reason states that "Quartz glass has long-range order." - This is also incorrect because amorphous solids, including quartz glass, do not exhibit long-range order in their atomic arrangement. 4. **Conclusion**: - Since both the assertion and the reason are incorrect, we conclude that the correct answer is that both the assertion and reason are false. ### Final Answer: Both assertion and reason are false. ---
