One issue of Custom tag

One issue in Custom tag :

Which two are concerning the objects available to developers creating tag files?

A.The session object must be declared explicity.
B.The request and response objects are available implicity.
C.The output stream is available through the implicit outStream object.
D.The servlet context is available through the implicit servletContext object.
E.The JspContext for the tag file is available through the implicit jspContext object.

Multiple choice,actually i have doubts of this question ?!

In the tag file ,it is forbidden to use scriptlet ,so how could it use JSP implicit object

Thanks a lot

Those are not accessed using scriptlets. Some implicit objects are also available to Tag Files. You'll find a complete list at section "JSP.8.8 Implicit Objects" of the JSP specification.
