D

View Answer
Correct Answer: D — Namespace
Explanation:
An XML namespace associates element and attribute names with a URI (Uniform Resource Identifier), ensuring global uniqueness and preventing naming conflicts when combining XML documents from different sources. Namespace declarations are typically placed on the root element using the 'xmlns' attribute, and all elements sharing a prefix belong to that namespace.
