Diode I-V Characteristic Curve

Steps:

• Identify forward bias region: Current increases exponentially with voltage for V > 0.
• Identify reverse bias region: Negligible current until breakdown voltage.
• Compare graph to ideal diode behavior: Sharp turn-on at ~0.7V for silicon, near-zero reverse current.
• Select option matching exponential forward and flat reverse curve.

Not enough information: Graph and choice descriptions are missing, preventing specific analysis.

Final answer: Not enough information.
