Why each option

Single sign-on (SSO) enables users to authenticate once for access to multiple independent systems, a concept distinct from identity consolidation.

ASingle sign-on is different than identity consolidation.Correct

SSO is a specific authentication mechanism allowing a single authentication event to grant access to multiple applications without re-entering credentials. Identity consolidation, while often a foundational step for SSO, focuses on centralizing user identity management across systems, making it a related but separate concept.

BSingle sign-on requires sending the same credentials to several services.

SSO aims to eliminate repeated credential sending by using a single authentication and subsequent tokens or assertions.

CSingle sign-on requires that the credentials for different services are distinct.

SSO typically relies on a unified identity and credentials, not distinct ones, to enable seamless access.

DSingle sign-on requires a smartcard.

While smartcards can be used for authentication in an SSO system, they are not a universal requirement for SSO implementation.
