B Correct answer
Explanation

The reference monitor is the security concept that mediates all accesses to objects by subjects, making access control decisions.

Resource managers handle resource allocation, suspended programs are inactive processes, and access control matrix is a model for organizing permissions, not the decision mechanism itself.
