For forward bias of p-n diode:

ANo bias
Bp connected to negative
CReverse
Dp side to positive terminal, n side to negative
Answer & Solution
Correct answer: D. p side to positive terminal, n side to negative
**Forward bias:** p to +, n to -. Reduces barrier height at junction. Current flows easily once V > V_barrier (≈0.7 V for Si, 0.3 V for Ge). Diode characteristic curve is exponential (Shockley).
