Explanation: Declarative security applies the security policies on the software applications at their runtime.
In this type of security, the security decisions are based on explicit statements that confine security behavior. Declarative security applies security permissions that are required for the software application to access the local resources and provides role-based access control to an individual software component and software application. It is employed in a layer that relies outside of the software code or uses attributes of the code. AnswerC is incorrect. In declarative security, authentication decisions are coarse-grained in nature from an operational or external security perspective.
