Wait, I'm a bit confused. I know a PKI has something to do with security, but I'm not sure how it relates to the specific options here. I'll need to review my notes on PKI to make sure I understand it properly before answering.

Okay, I've got this. A PKI provides the infrastructure and processes to issue, manage, and revoke digital certificates. That allows for secure authentication and data encryption. I'm pretty confident option C is the right answer.

I think the key here is understanding what a PKI actually does. The options mention things like digital signatures, security for web-based businesses, and defining public keys, so I'll need to focus on those concepts.
