Why each option
PKI (Public Key Infrastructure) is the framework specifically built around the issuance, management, and validation of digital certificates to establish trust and secure communications.
Kerberos uses symmetric key cryptography and tickets issued by a KDC, not digital certificates, for authentication.
LDAP is a directory access protocol used to query and modify directory information and does not use certificates as its security mechanism.
PKI is a system of hardware, software, policies, and procedures that manages digital certificates and public-private key pairs. Certificates issued by a Certificate Authority (CA) are the core mechanism PKI uses to authenticate identities, encrypt data, and establish secure channels such as TLS/SSL. Every PKI transaction depends on certificate validation through a chain of trust.
CHAP authenticates using a three-way challenge-response handshake with a shared secret, not certificates.
