The correct answer is B. REST Connector . Saviynt documentation explains that REST integration is intended for applications whose data and lifecycle actions are available through REST endpoints. It states that the REST integration enables organizations to gain visibility, manage the user lifecycle, and govern access for data available in the REST application or REST endpoint. That directly matches the question, which requires imports plus provisioning and deprovisioning for an API-driven target system.

Saviynt’s REST connector documentation also notes that provisioning and deprovisioning are supported when the connection is configured correctly. This makes the REST connector the standard choice when the target system does not use an out-of-the-box native connector but does provide usable REST APIs. The other options do not fit the requirement. Active Directory Connector is specific to AD use cases, SMTP Configuration is only for email delivery, and Dataset Configuration is an administrative data-structuring feature rather than an application integration method. In Saviynt Level 200 terms, when an application is API-first and lifecycle actions must be automated, the REST connector is the appropriate design decision.
