This information mustNOT be accessible to any other servlet， JSP or session in the webapp. How can you accomplish this goal？（）
A
Store the data in a public instance variable in the servlet.
B
Add an attribute to the request object before using the request dispatcher.
C
Add an attribute to the context object before using the request dispatcher.
D
This CANNOT be done as the tag handler has no means to extract this data.
