You are creating a content management system （CMS） with a web application front-end. The JSP thatdisplays a given document in the CMS has the following general structure：
1. <%-- tag declaration --%>
2. <t：document>
...
11. <t：paragraph>... <t：citation docID=’xyz’ /> ...</t：paragraph> ...
99. </t：document>
The citation tag must store information in the document tag for the document tag to generate a referencesection at the end of the generated web page. The document tag handler follows the Classic tag model andthe citation tag handler follows the Simple tag model. Furthermore， the citation tag could also be embeddedin other custom tags that could have either the Classic or Simple tag handler model.
Which tag handlermethod allows the citation tag to access the document tag？（）
A.public void doTag（） {JspTag docTag = findAncestorWithClass（this， DocumentTag.class）； （（DocumentTag）docTag）.addCitation（this.docID）；}
B.public void doStartTag（） {JspTag docTag = findAncestorWithClass（this， DocumentTag.class）； （（DocumentTag）docTag）.addCitation（this.docID）；}
C.public void doTag（） {. Tag docTag = findAncestor（this， DocumentTag.class）； . （（DocumentTag）docTag）.addCitation（this.docID）；. }
D.public void doStartTag（） {. Tag docTag = findAncestor（this， DocumentTag.class）； . （（DocumentTag）docTag）.addCitation（this.docID）；. }

You have built your own light-weight templating mechanism. Your servlets， which handle each request，dispatch the request to one of a small set of template JSP pages. Each template JSP controls the layout ofthe view by inserting the header， body， and footer elements into specific locations within the template page.The URLs for these three elements are stored in request scoped variables called， headerURL， bodyURL，and footerURL， respectively. These attribute names are never used for other purposes.
Which JSP codesnippet should be used in the template JSP to insert the JSP content for the body of the page？（）
A.<jsp：insert page=’${bodyURL}’ />
B.<jsp：insert file=’${bodyURL}’ />
C.<jsp：include page=’${bodyURL}’ />
D.<jsp：include file=’${bodyURL}’ />
E.<jsp：insert page=’<%= bodyURL %>’ />
