10.<head>
11.<script src='/scripts/screenFunctions.jsp'
12.language='javascript'

You have decided to remove this redundant HTML code from your JSPs and put it into a single JSP called /WEB-INF/jsp/header.jsp. However, the title of each page is unique, so you have decided 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 the pageTitle variable?
- A. <jsp:insert page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:insert> - B. <jsp:include file='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include> - C. <jsp:include page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include> - D. <jsp:include page='/WEB-INF/jsp/header.jsp'>
<jsp:param name='pageTitle' value='Welcome Page' />
