• C{ "books": { "science": { "biology": "10.00", "geology": "9.00", "chemistry": "8.00" }, "math": { "calculus": "20.00", "algebra": "12.00" } } }
• D{ "books": { "science": { "biology": "10.00", "geology": "9.00", "chemistry": "8.00" }, "math": { "calculus": "20.00", "algebra": "12.00" } } }

Explanation

Converting XML-encoded hierarchical data to its JSON equivalent requires correctly mapping nested XML elements to nested JSON objects with matching key-value pairs.

Common mistakes.

• A. Choice A incorrectly structures or orders the JSON object such that it does not faithfully replicate the hierarchy or values present in the source XML.
• B. Choice B contains a structural or value mismatch that does not accurately reflect the nesting and data from the original XML-encoded document.
• D. Choice D misrepresents the XML data by using an incorrect structure or incorrect key-value assignments that diverge from the source XML.
