doubt regarding mock exam question

Hi all,

I have found this question in one mock exam (java certificate question no.5).

Select one correct answer from the following:-
A.The order of elements in deployment descriptor is important. The elements must follow a specific order.
B The elements of deployment descriptor are not case insensitive
C The servlet-mapping element, if defined, must be included within the servlet element.
D The web-app element must include the servlet element

The answer given is A. But I thinks that, the order doesn't matter. Also, the elements in DD is case sensitive. So my answer is B. Can anyone clarify this.

"A" would be correct answer in version 1.3 but it is not true for 1.4, which is the current version of the exam.

"B" is not correct because it reads exactly opposite to the truth.
