When a diode is switched from forward to reverse bias, storage and transition times takes place. The accumulation time or the life time of minority carriers makes it a short circuit. The conduction property is holds for a short period of time in reverse bias also.

Explanation:

1) In reverse bias, the diode undergoes stages of storage and transition times:
- When a diode is in reverse bias, it goes through stages of storage and transition times.
- During the storage time, the diode stores the charges in the depletion region.
- Transition time occurs when the charges start to recombine and the diode transitions from the conducting state to the non-conducting state.
- These stages are important for the proper functioning of the diode in reverse bias.

2) Minority charge carriers accumulation makes the diode as a short circuit:
- In a diode, when minority charge carriers accumulate in the depletion region, it can behave like a short circuit.
- This can lead to a significant current flow through the diode, which can damage the diode if not controlled properly.
- Therefore, it is important to prevent excessive minority charge carrier accumulation in the diode.

3) Storage time is the sum of recovery and transition times:
- The storage time in a diode is a combination of the recovery time and the transition time.
- Recovery time is the time taken for the charges stored in the depletion region to recombine and the diode to recover its non-conducting state.
- Transition time is the time taken for the diode to transition from the conducting state to the non-conducting state.
- Therefore, the storage time is the sum of these two times and is crucial for understanding the behavior of the diode in reverse bias.
Therefore, options 1 and 2 are true, making option 'D' the correct answer.
