单项选择题A customer stores environmental settings in the deployment descriptors of an application. Whenever they promote the application version from testing to the production environment, they need to open the archive and modify the deployment descriptor. This process is against their security policy.    What approach should you recommend to leverage WebLogic features such that they do not have to modify the application archive for different environments?（）

A.Keep environmental data in the global settings of domain and the application can read it from the domain where it runs.
B.Keep environmental data in Deployment Plan XML files. It allows you to change parameters in the deployment descriptor without opening the archive file.
C.Keep environmental data in the database because it is the most effective way of parametrizing the environment.  
D.Keep archive in exploded format so the customer does not have to open the archive files.
E.Eliminate all environmental settings from the application. There should not to be any environmental settings in the application.
