Why each option
A PKI key pair is an asymmetric cryptographic pair consisting of a public key and a private key that are mathematically linked.
A key ring is a storage container or keychain used to manage multiple keys, not a component of a key pair.
The public key is the shareable half of the asymmetric key pair, distributed openly so others can encrypt data or verify signatures.
The private key is the secret half of the pair, kept exclusively by the owner to decrypt data or create digital signatures; together these two keys form the key pair.
Key escrow is a process of storing a copy of a key with a trusted third party for recovery purposes, not part of the key pair itself.
A passphrase may be used to protect a private key file but is not itself a component of the cryptographic key pair.
