WAR File Doubt

Which of the following statements is true?

A. A war file is an xml configuration file
B. a war file must contain a directory called META-INF
C. a war file can contain servlets but not jsp pages
D. a war file can contain servlets, jsp and other resources
E. The top directory of a war file is the document root of the application

Answer given in marcus mock: B,D,E

But I think B is wrong , a WAR must contain META-INF only when it is required to specify dependencies otherwise not required.
also I think E is wrong, not the top directory but the contents in the WAR file are unpackaged and become the root of web application.

SRV.9.6 Web Application Archive File

Web applications can be packaged and signed into a Web ARchive format (WAR) file using the standard Java archive tools. When packaged into such a form, a META-INF directory will be present which contains information useful to Java archive tools.

In normal circuimstances you will have both a META-INF and a WEB-INF dir in your war file although it is not mandated by the specs.

For the exam you won't get questions about the presence of these directories, and if you do, you should consider them to be there.
