An access control matrix is a table that specifies what actions are allowed for particular users or groups. It shows the matrix of permissions, with the rows representing the subjects (users, processes, etc.), the columns representing the objects (files, databases, etc.), and the entries indicating the permissions of subjects on objects. Thus, option D is the correct choice. Options A, B, and C describe the process of access control in general, but not specifically the access control matrix.
