Answer 1

The correct answer is (a) XACML.

XACML (eXtensible Access Control Markup Language) is a policy language that allows a distributed identity system to write and enforce custom policy expressions. It provides a standard for expressing security policies related to access control and allows for fine-grained authorization decisions. XACML is widely used for specifying access control rules in cloud computing environments and other distributed systems.
