Correct answer: A
Answer: Document Type Definition (DTD).
Explanation: The DOCTYPE declaration in an XML document specifies a reference to a Document Type Definition (DTD). A DTD defines the allowed elements, attributes, and overall structure of the XML document. The DTD can be included internally or referenced as an external .dtd file.
External DTD: referenced using SYSTEM or PUBLIC, for example: <!DOCTYPE root SYSTEM "example.dtd">
Internal DTD: the DTD rules are placed directly inside the DOCTYPE declaration (internal subset).
Purpose: DTDs are used for validation and to ensure the XML document follows the expected structure.
