Correct answer & explanation

✓

Dictionary

JSON objects map directly to Python dictionaries. Option B (Tuple) is wrong because tuples are immutable and lack key-value mapping. Option C (String) is wrong because a string would lose all structure, making access by key impossible. Option D (List) is wrong because lists are ordered sequences accessed by index, not by key-value pairs.
