As Anonymous indicates, the answer should be “C”
“The APIC REST API is a programmatic interface to the Application Policy Infrastructure Controller (APIC) that uses a Representational State Transfer (REST) architecture. The API accepts and returns HTTP or HTTPS messages that contain JavaScript Object Notation (JSON) or Extensible Markup Language (XML) documents. You can use any programming language to generate the messages and the JSON or XML documents that contain the API methods or managed object (MO) descriptions.
The API model includes these programmatic entities:
Classes—Templates that define the properties and states of objects in the management information tree.
Methods—Actions that the API performs on one or more objects.
Types—Object properties that map values to the object state (for example, equipmentPresence).”
