The Correct Option is B
Solution and Explanation
Zener diodes are specially designed junction diodes, which can operate in the reverse breakdown voltage region continuously without being damaged. This breakdown voltage occur when reverse bias is increased beyond a particular value, the reverse current increases suddenly on increasing the reverse bias even slightly. In normal diode after this breakdown voltage, low power
rating will get destroyed but Zener diode is specially designed to work in this region of biasing.
