Answer: C
Explanation: [from red book]
  3.2.8 Intelligent runtime provisioning
Intelligent runtime provisioning is a concept that was introduced with WebSphere Application Server V7. This mechanism selects only the runtime functions that are needed for an application. Each application is examined by WebSphere Application Server during deployment to generate an activation plan as shown in Figure. At run time, the application server uses the activation plan to start only those components that are required inside the application server. This process can reduce the runtime footprint, and can significantly reduce startup times.
