The correct Answer is:
To solve the question regarding the preference of silicon over germanium in constructing zener diodes, we will analyze both the assertion (A) and the reason (R) provided. ### Step 1: Understand the Assertion (A) The assertion states: "Silicon is preferred to germanium while constructing zener diodes." - **Explanation**: Silicon is indeed the preferred material for zener diodes due to its superior electrical properties, particularly in terms of breakdown voltage and stability. ### Step 2: Understand the Reason (R) The reason states: "Thermal stability and current compatibility of silicon is high when compared to those of germanium." - **Explanation**: Silicon has better thermal stability than germanium. This means that silicon can operate at higher temperatures without degrading its performance. Additionally, silicon has a higher current carrying capacity, making it more reliable in various applications. ### Step 3: Evaluate the Relationship Between A and R Now we need to determine if the reason (R) correctly explains the assertion (A). - **Analysis**: The reason provided supports the assertion since the thermal stability and current compatibility of silicon are indeed key factors that make it preferable over germanium for zener diodes. ### Step 4: Conclusion Both the assertion (A) and the reason (R) are true, and the reason correctly explains why silicon is preferred over germanium. ### Final Answer The correct answer is: **Option A: Both A and R are true, and R is the correct explanation of A.** ---
