A small company wants to employ PKI. The company wants a cost effective solution that must be
simple and trusted. They are considering two options: X.509 and PGP. Which of the following
would be the BEST option?

A.
PGP, because it employs a web-of-trust that is the most trusted form of PKI.

B.
PGP, because it is simple to incorporate into a small environment.

C.
X.509, because it uses a hierarchical design that is the most trusted form of PKI.

D.
X.509, because it is simple to incorporate into a small environment.
