The correct answer is the multi-domain certificate. This type of SSL certificate is designed specifically to secure multiple domain names under a single certificate. It offers flexibility in protecting various websites without the need for separate certificates for each domain, making it a convenient choice for organizations that manage several domains or subdomains.

Wildcard certificates, while they allow for securing multiple subdomains of a single primary domain, do not cover entirely different domain names. Single-domain certificates are limited to protecting only one specific domain, and extended validation certificates are focused on providing a higher level of identity verification for a single domain, rather than multiple domains. The multi-domain certificate uniquely addresses the need to secure multiple unrelated domain names simultaneously, making it optimal for many businesses with diverse web presences.
