The Correct Option is B
Solution and Explanation
Concept:
A diode allows current to flow easily in one direction and blocks current in the opposite direction.
Step 1: In forward bias, the positive terminal is connected to \(P\)-side and negative terminal to \(N\)-side.
Step 2: This reduces the depletion barrier.
Step 3: Majority carriers cross the junction easily.
Step 4: Hence, current flows through the diode. Therefore: \[ \boxed{\text{Forward biased}} \]
