A customer has multiple application servers which create one process for each connected user.  All users share the same AIX environment. What is a benefit of using WPARs in this environment？（）

A.WPARs give more controls for resource management than the traditional AIX operating system tools.

B.WPARs support Live Application Mobility which can be used to balance user processes acrosssystems.

C.WPARs each have a copy of the AIX kernel， offering better availability than a system without WPARs.

D.WPARs provide the ability to apply fixes specific for each environment， enabling the customer to create specialized application servers.
