A risk register is a document that lists all the identified risks to an organization's assets, along with the potential impact and likelihood of each risk occurring, and the measures in place to address them.

Option A, an SLA document, is a contract between a service provider and a customer that outlines the level of service expected by the customer. It is not directly related to security management programs or the identification of assets with identified deviations and mitigation measures.

Option B, a DR plan, is a plan that outlines the procedures and strategies for recovering an organization's IT infrastructure and operations in the event of a disaster. While it is an essential document for an organization's business continuity, it is not directly related to the CISO's requirements of identifying assets with deviations and mitigation measures.
