Correct Answer: D

Explanation:
No recovery key = no recovery. Time to install.
Any other option defeats the whole point of encrypting it. Encrypted volumes are locked when the encryption key is not available. When the operating system volume is locked, you can boot only to recovery mode. In recovery mode, you can enter the BitLocker password or you can attach the USB device that has the recovery key stored and restart the computer. Once you enter the recovery password or key, you can boot your computer normally.
The following events trigger recovery mode:
* The boot environment changes. This could include one of the boot files being modified.
* TPM is disabled or cleared.
* An attempt is made to boot without the TPM, PIN, or USB key being provided.
* You attach a BitLocker-encrypted operating system volume to another computer.
