Answer: D
A digital signature includes an encrypted hash total of the
size of the message as it was transmitted by its originator.
This hash would no longer be accurate if the message was
subsequently altered, thus indicating that the alteration
had occurred. Digital signatures will not identify or
prevent any of the other options. The signature would
neither prevent nor deter unauthorized reading, copying or
theft.
