Explanation

JSP pages have access to the config implicit object (ServletConfig) and can call getInitParameter() on it (option D). Within a JSP declaration or scriptlet, you can also directly call getInitParameter() (option B) because it's inherited from HttpJspBase/Servlet. Options A and E retrieve request parameters (wrong scope). Option C uses application (ServletContext), which retrieves context-wide init params, not JSP-specific ones.
