To take advantage of the capabilities of modern browsers that use web standards， such as XHTML andCSS， your web application is being converted from simple JSP pages to JSP Document format. However，one of your JSPs， /scripts/screenFunctions.jsp， generates a JavaScript file. This file is included in severalweb forms to create screen-specific validation functions and are included in these pages with the followingstatement：
10.<head>
11.<script src='/scripts/screenFunctions.jsp'
12.language='javascript'
13.type='application/javascript'> </script>
14.</head>
15.<!-- body of the web form -->
Which JSP code snippet declares that this JSP Document is a JavaScript file？（）
A.<%@ page contentType=’application/javascript’ %>
B.<jsp:page contentType='application/javascript' />
C.<jsp:document contentType='application/javascript' />
D.
E.No declaration is needed because the web form XHTML page already declares the MIME type of the /scripts/screenFunctions.jsp file in the <script> tag.
