Answer: D - Domain is defined as a set of objects that a subject is able to access. This domain can be all the resources a user can access, all the files available to a program, the memory segments available to a process, or the services and processes available to an application. A subject needs to be able to access and use objects to perform tasks and the domain defines which objects are available to the subject and which objects are untouchable and therefore unusable by the subject.
