Answer: A
A RA is an entity that is responsible for identification and
authentication of certificate subjects, but the RA does not
sign or issue certificates. The certificate subject usually
interacts with the RA for completing the process of
subscribing to the services of the certification authority
in terms of getting identity validated with standard
identification documents, as detailed in the certificate
policies of the CA. In the context of a particular
certificate, the issuing CA is the CA that issued the
certificate. In the context of a particular CA certificate,
the subject CA is the CA whose public key is certified in
the certificate.
