In an emergency, it is essential that planning records are stored in a format that allows for quick and efficient retrieval. The correct answer indicates that all the mentioned formats—microfilm, microfiche, and computer tapes—can be valid for storing records in an emergency situation.

Each format has its own advantages. Microfilm and microfiche are physical media that can be useful for archiving documents in a compact form, providing a tangible backup that is not reliant on digital infrastructure. In certain circumstances, such as a power failure or digital system malfunction, these formats can still be accessed.

Computer tapes, on the other hand, are widely used for digital backup and can store large volumes of data efficiently. They can be restored to retrieve vital information, provided that the necessary equipment is available.

The effectiveness of records in an emergency is contingent upon having multiple formats available because it enhances redundancy. This ensures that if one method fails or becomes inaccessible, others remain viable for use. Therefore, having records in any of these formats is prudent, corroborating that the best choice is one that encompasses all options.
