• A.<jsp:if test= 'request.isUserInRole("SalesManager")'><jsp:include file
  '/WEB-INF/html/sales-mgr-menu.html' /></jsp:if>
• B.<% if ( request.isUserInRole("SalesManager") ) { %><jsp:include
  file='/WEB-INF/html/sales-mgr-menu.html' /><% } %>
• C.<% if (request.isUserInRole ("SalesManager") ) { %><%@ include file='
  /WEB-INF/html/sales-mgr-menu.html' %><% } %>
• D.<jsp:if test= 'request.isUserInRole ("SalesManager") '><%@ include file
  '/WEB-INF/html/sales-mgr-menu.html' /%></jsp:if>
