The P-N junction diode conducts in which direction.a)Reverse direction...
The P-N junction diode conducts only in forward direction, it will not conduct in reverse direction so only Zener Diode was introduced as it conducts in both forward and reverse direction.

The P-N junction diode conducts in which direction.a)Reverse direction...
Explanation:
A P-N junction diode is a two-terminal electrical component that allows the flow of electric current in only one direction. It is made up of two types of semiconductor materials, P-type (positive) and N-type (negative).
Forward Direction:
When the P-type material is connected to the positive terminal and the N-type material is connected to the negative terminal of a battery or voltage source, it is said to be in forward bias. In this condition, the diode allows the flow of electric current through it, and the current flows from the P-type material to the N-type material.
Reverse Direction:
When the P-type material is connected to the negative terminal and the N-type material is connected to the positive terminal of a battery or voltage source, it is said to be in reverse bias. In this condition, the diode does not allow the flow of electric current through it, and the current does not flow from the N-type material to the P-type material.
Conclusion:
Thus, the P-N junction diode conducts only in the forward direction and does not conduct in the reverse direction. Hence, the correct answer is option B, i.e., Forward direction.
