Which invocation on the pageContext object, inserted at line 6, assigns "bar" to the variable x?

Given the JSP code:
<% request.setAttribute(“foo”, “bar”); %>
and the Classic tag handler code:
5. public int doStartTag() throws JspException {
6. // insert code here
7. // return int
8. }
Assume there are no other “foo” attributes in the web application.
Which invocation on the pageContext object, inserted at line 6, assigns “bar” to the variable x?

A.
String x = (String) pageContext.getAttribute(“foo”);

B.
String x = (String) pageContext.getRequestScope(“foo”);

C.
It is NOT possible to access the pageContext object from within doStartTag.

D.
String x = (String)
pageContext.getRequest().getAttribute(“foo”);

E.
String x = (String) pageContext.getAttribute(“foo”,
PageContext.ANY_SCOPE);
