Your web application views all have the same header， which includes the <title> tag in the <head> elementof the rendered HTML. You have decided to remove this redundant HTML code from your JSPs and put itinto a single JSP called /WEB-INF/jsp/header.jsp. However， the title of each page is unique， so you havedecided to use a variable called pageTitle to parameterize this in the header JSP， like this：
10.<title>${param.pageTitle}<title>
Which JSP code snippet should you use in your main view JSPs to insert the header and pass thepageTitle variable？（）
A.<jsp：insert page=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：insert>
B.<jsp：include page=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：include>
C.<jsp：include file=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：include>
D.<jsp：insert page=’/WEB-INF/jsp/header.jsp’>. <jsp：param name=’pageTitle’ value=’Welcome Page’ /> . </jsp：insert>
E.<jsp：include page=’/WEB-INF/jsp/header.jsp’>. <jsp：param name=’pageTitle’ value=’Welcome Page’ /> . </jsp：include>

Next， the Front Controller servlet must send the request to this JSP togenerate the view. Assume that the servlet variable request is assigned the current HttpServletRequestobject and the variable context is assigned the webapp’s ServletContext.Which code snippet of the FrontController servlet accomplishes this goal？（）
