Explanation

A Certificate Revocation List (CRL) is a signed list published by a Certificate Authority (CA) that enumerates digital certificates that have been revoked before their natural expiration date-due to key compromise, CA compromise, or other reasons. Once a certificate appears on the CRL, it must be treated as untrusted regardless of whether it is otherwise unexpired or structurally valid. Option A is wrong because the CRL lists untrusted certs, not trusted ones. Option B describes a certificate chain/path, not a CRL. Option C is unrelated-CRLs contain no alternate device identifiers. OCSP (Online Certificate Status Protocol) is the modern alternative to CRLs for real-time revocation checking.
