Explanation

XML (eXtensible Markup Language) uses a tag-based syntax where data is wrapped in opening and closing tags (e.g., <name>value</name>), organized into elements, and can include attributes within tags (e.g., <user id='1'>). JSON (JavaScript Object Notation) represents data as collections: objects are unordered sets of key-value pairs enclosed in curly braces {}, and arrays are ordered lists enclosed in square brackets []. Choice A incorrectly reverses the descriptions, attributing tags/elements/attributes to JSON. Choice B incorrectly states JSON objects are ordered (they are unordered) and confuses XML arrays (XML has no native array type). Choice D incorrectly describes JSON arrays as unordered key-value pairs (arrays are ordered lists, not key-value pairs).
