Answer: D
If the certificate authority belongs to the same
organization, this would generate a conflict of interest. If
a customer wanted to repudiate a transaction, he/she could
allege that there exists an unlawful agreement between the
parties generating the certificates, because of the shared
interests. If a customer wanted to repudiate a transaction,
he/she could believe that there exists a bribery between the
parties to generate the certificates, as there exist shared
interests. The other options are not weaknesses.
