Why each option
A Certificate Authority (CA) is a trusted third party that issues digital certificates to bind public keys to entity identities, enabling digital signatures and PKI-based trust.
CAs are not non-profit standard-setting organizations - that role belongs to bodies like NIST or ISO, while CAs are commercial or enterprise entities focused on certificate issuance.
CAs issue digital (electronic) certificates stored as data files containing public keys and identity metadata, not physical certificates.
A CA has no relationship to B2C commerce models - it is an identity and cryptographic trust infrastructure component, not a business transaction framework.
A CA is a trusted third-party organization that issues digital certificates binding a public key to a verified entity, allowing that entity to prove its identity and create digital signatures. CAs are the cornerstone of Public Key Infrastructure (PKI), and examples include DigiCert, Let's Encrypt, and Microsoft Active Directory Certificate Services. Without a CA, there is no trusted mechanism to validate that a public key actually belongs to the claimed party.
