Explanation

Option C is correctly formatted JSON because it uses proper JSON array syntax with square brackets, contains a valid object enclosed in curly braces, uses correctly quoted key-value string pairs, and - critically - has NO trailing comma after the last property ('session':'fall'). Trailing commas after the final key-value pair in a JSON object are a syntax error in strict JSON formatting, which eliminates options A and B. Option D is missing the closing bracket for the array.
