What is the risk if the key for an encrypted file is lost?

Answer and explanation

Correct answer: Even an authorised user may be unable to open the file

The governing concept is key-dependent access control. An encrypted file can normally be read only after the correct encryption key, password, or recovery credential is supplied. If that key is lost and no valid recovery method exists, even the legitimate owner may be unable to decrypt and open the data. Losing a key does not decompress a file, damage a monitor, or improve operating-system speed. Therefore, option A is correct.
