Which of the following is an example of a BitLocker recovery password?

This string contains non-numeric characters such as 'J' and 'I', which are never present in a BitLocker recovery password since it is strictly numeric.

BitLocker generates recovery passwords in a fixed format: exactly 48 numeric digits arranged in 8 groups of 6 digits each. Option B contains precisely 8 six-digit numeric groups (389627, 801256, 690151, 785527, 909978, 568638, 271012, 905516), matching this format exactly. This is the only format Windows accepts as a valid BitLocker recovery password.

This is a hexadecimal hash string resembling an MD5 digest, not the 48-digit numeric group format that BitLocker uses.

This is a Base64-encoded string, a format used for binary-to-text encoding, which has no relation to the BitLocker recovery password structure.
