Correct option is (a) True

Easiest explanation: Yes, this is a true statement. The I-V characteristics of a LED are indeed similar to that of Si junction diode. But the threshold voltages are much higher and slightly different for each color. The reverse breakdown voltages of LEDs are very low, typically around 5 V.
