In Zener breakdown, the depletion region of a pn junction diode is wider. So, the correct answer is d) wider.

Here's a step-by-step explanation:

1. The Zener breakdown occurs in a heavily doped pn junction diode, which has a narrow depletion region.

2. When the reverse bias voltage applied to the diode is increased, the electric field across the depletion region also increases.

3. At a certain high level of reverse bias voltage, the electric field becomes so strong that it can pull electrons from their valence bands and make them free. This process is known as the Zener breakdown.

4. During this process, the depletion region becomes wider due to the increase in the number of free electrons and holes.

So, in the Zener breakdown, the depletion region of a pn junction diode becomes wider.
