Special Purpose Diodes question from JEE Main 2022 (28 Jul, Shift 1)

Answer: (b)

1. A solar cell supplies current without external bias, so its curve lies in the fourth quadrant (V positive, I negative).
2. Graph (b) shows the curve from short-circuit current on the $-I$ axis to open-circuit voltage on the $V$ axis.
3. (a) is a diode, (c) is a resistor, (d) is a Zener diode.
4. So the answer is (b).
