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>
