LM hashes are split into two 16-character halves (each representing 7-character blocks). If the original password is less than 8 characters, the second half of the LM hash will always be a constant:
"AAD3B435B51404EE"
This known value is used to pad the second half of the password, and it signals that the original password was 7 characters or fewer.
In the options:
B. 44EFCE164AB921CQAAD3B435B51404EE ← ends with AAD3B435B51404EE → < 8 chars
E. B757BF5C0D87772FAAD3B435B51404EE ← also ends with AAD3B435B51404EE → < 8 chars
