What is the I-V characteristic curve of a PN junction diode?

The I-V characteristic curve of a PN junction diode shows exponential increase in current with forward voltage and a small reverse saturation current.

The I-V curve indicates a decrease in current with increasing forward voltage.

The I-V curve is linear with no reverse current.

The I-V characteristic shows a constant current regardless of voltage.
