Explanation

JSON Syntax Explained

Option C is correct because it follows all valid JSON rules: it uses double quotes for all keys and string values, uses curly braces {} for objects, uses square brackets [] for arrays, and properly nests the inner object with correct comma-separated key-value pairs.

Why the others are wrong:

• Option A is missing the curly braces {} around the nested object - "name":"dist1" is just floating inside the outer object without being wrapped in its own object structure
• Option B uses single quotes instead of double quotes (JSON requires double quotes), and uses parentheses () instead of curly braces {} for the nested object
• Option D uses forward slashes (/) around key names, which is not valid JSON syntax at all - keys must simply be enclosed in double quotes with no extra characters

Memory Tip: Think of JSON as being very strict and picky - it only accepts double quotes (never single), uses {} for objects and [] for arrays, and never uses special characters like slashes in key names. A common exam trap is substituting single quotes or parentheses, which are valid in Python but not in JSON.
