   An organization has an Ansible inventory with multiple groups. The administrator needs to run a playbook that applies a common configuration to all servers, but also needs to apply a specific configuration to a subset of servers in the 'web' group. How should the playbook be structured to achieve this efficiently?

   • AUse a single play that targets 'all' hosts and include a conditional 'when' statement to apply the web-specific configuration only to hosts in the 'web' group.
   • BUse a single playbook with two plays: the first play targets 'all' hosts for the common configuration, and the second play targets the 'web' group for the specific configuration.
   • CCreate two separate playbooks: one for the common configuration and one for the web-specific configuration.
   • DUse a single play that targets 'all' hosts and use the 'include_tasks' module to conditionally include the web-specific tasks.
