The correct answer is Object.

An Object in access control is the item that a user or application performs actions on. It is the target of access requests and can be a file, a database record, a device, a service, or other tangible items managed by the system. Access control models make decisions about which subjects may perform which operations on objects under specified conditions.

Actor is incorrect because an actor is the initiator of actions or requests rather than the target. Actors are subjects such as users, processes, or systems and so the term does not name the item being acted upon.

Resource is not the expected answer here because resource is a broader and sometimes interchangeable term. Many formal access control definitions and exam questions use the specific term object to mean the item being acted on and so resource is not the preferred technical term in this context.

Entity is incorrect because entity is a generic term that can refer to either subjects or objects and it does not specifically denote the target of actions in access control terminology.
