  3. Cforward bias and in parallel with load.
  4. Dreverse bias and in parallel with load.

Correct answer

A. reverse bias and in series with load.

Step-by-step solution

A Zener diode functions as a voltage regulator by maintaining a constant output voltage across a load during reverse breakdown operation. In this region, the voltage remains stable at V_Z across a wide current range, requiring reverse bias connection. To regulate load voltage, the diode is connected in parallel with the load, ensuring V_Z appears directly across it. A series resistor limits current and drops excess input voltage. The correct configuration is therefore reverse bias and parallel connection , making o
