Question:
Which of these is true about deployment descriptors. Select one correct answer.

Option A):
The web-app element must include the servlet element
Option B):
The order of elements in deployment descriptor is important. The elements must follow a specific order.
Option C):
The servlet-mapping element, if defined, must be included within the servlet element.
Option D):

Correct Answer is Option B):
The order of elements in deployment descriptor is important. The elements must follow a specific order.

Explanation:
The servlet specifications specifies a specific order of deployment descriptor. The elements of deployment descriptor are not case insensitive is incorrect because elements are case-sensitive. The servlet-mapping element should be included within the <WEB-APP>element. So The servlet-mapping element, if defined, must be included within the servlet element is incorrect. All the elements within the web-app element are optional. So The web-app element must include the servlet element is incorrect.
