D is the Correct Answer.
A. It is common to use a single certificate authority (CA). They do not need to be geographically dispersed.
B. The use of public key infrastructure (PKI) and certificates allows flexible secure communications from many devices.
C. The CA will often have redundancy and failover capabilities to alternate data centers.
D. If the CA belongs to the same organization, this would pose a risk. The management of a CA must be based on trusted and secure procedures. If the organization has not set in place the controls to manage the registration, distribution and revocation of certificates this could lead to a compromise of the certificates and loss of trust.
