Explanation

In PKI (Public Key Infrastructure), a Certificate Authority (CA) is the trusted entity responsible for issuing digital certificates, which bind a public key to an identity (person, server, or organization) and are signed by the CA to prove authenticity. Option B is wrong because SAML keys are part of the SAML federation protocol for SSO authentication, not issued by a CA. Option C is wrong because KDC (Key Distribution Center) tickets - like Kerberos TGTs - are issued by a KDC in Kerberos environments, a completely separate authentication system. Option D is wrong because shared (symmetric) keys are negotiated between parties directly (e.g., via Diffie-Hellman) and are never "issued" by a CA.

Memory tip: Think of a CA like a government passport office - it certifies your identity by issuing a signed document (the digital certificate). CA = Certificate Authority = issues Certificates.
