Explanation

Kerberos uses symmetric (secret) key cryptography, so its database stores copies of users' secret (symmetric) keys - not public keys. Public keys belong to asymmetric (PKI) systems. The other statements are true: the KDC is a single point of failure (if it goes down, authentication fails); however, Kerberos handles authentication and ticket granting, not fine-grained access permissions (authorization); and it definitively uses symmetric cryptography.
