The part of the Varactor diode responsible for its capacitance is the c) depletion region.

Here's a step-by-step explanation:

1. A Varactor diode is a special type of diode which is designed to exploit the voltage-dependent capacitance of a reverse-biased p-n junction.

2. In a Varactor diode, when it is reverse-biased, the p-n junction's depletion region width increases.

3. The capacitance of the diode is inversely proportional to this depletion region width.

4. Therefore, as the reverse-bias voltage increases, the depletion region width also increases, which in turn decreases the capacitance.

5. Hence, the depletion region is the part of the Varactor diode that is responsible for its capacitance.
