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

Here's a step-by-step explanation:

1. The Zener breakdown occurs in a heavily doped pn junction diode, which has a very thin 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 electric field, the kinetic energy gained by the minority charge carriers (due to the strong electric field) is sufficient to knock out electrons from the covalent bonds, creating more electron-hole pairs.

4. This process is known as the Zener breakdown, and it leads to a sudden increase in the current through the diode.

5. During this process, the depletion region becomes wider due to the increase in the number of ionized donor and acceptor atoms.
