   A DevOps engineer runs an Ansible playbook that configures OSPF on a Cisco IOS router. The first run reports 'changed' for the OSPF task. The engineer runs the playbook again and the task reports 'ok' with no changes. What is the most likely reason for this behavior?

   • AThe OSPF process was removed and recreated between runs.
   • BThe OSPF configuration was applied to a different device on the second run.
   • CThe playbook uses the ios_command module, which caches the output of the first run.
   • DThe ios_config module is idempotent and only makes changes when the configuration differs from the desired state.
