This is the question on javaprepare.com.And explanation given is:
************************************************
# a. The servlet specifications specifies a specific order of deployment descriptor. b is incorrect because elements are case-sensitive. The servlet-mapping element should be included within the element. So c is incorrect. All the elements within the web-app element are optional. So d is incorrect.

a. The servlet specifications specifies a specific order of deployment descriptor.

May be correct with earlier versions of spec.

With servlet spec 2.4 elements can be of any order in web.xml.
