Answer: C
The public key is stored in the key servers and can be
accessed by anyone, and therefore, the holders of the public
key are unlikely to be included in the certificate. In
addition, the public key holder is not needed for validation
of the certificate. The name of the CA is needed for
validation of the certificate, since the public key of the
CA is needed to verify the public key of the message sender,
before it can be used to verify the message. The public key
of the sender is needed to verify the message hash, while
the time period for which the key is valid is needed to
ensure the key is still valid.
