The wireless LAN Controller is embedded into the access point is the correct answer.

In a Cisco Mobility Express network, Access Point (AP) running the wireless controller function is designated as the primary AP. The other Access Points which are managed by this primary AP are referred as Subordinate APs.
The primary AP has two roles:

1. It functions and operates as a wireless LAN controller to manage and control the Subordinate APs. The Subordinate APs operates as lightweight access points to serve clients.
   
2. Primary AP operates as an Access Point to serve clients.
