In a Zener diode, what happens to the P-N junction when it is reverse biased beyond the Zener breakdown voltage?

The P-N junction enters Zener breakdown, allowing reverse current to flow, maintaining a constant voltage.

The P-N junction stops conducting entirely.

The P-N junction allows current to flow freely without resistance.

The P-N junction generates light due to recombination of carriers.
