Question

Which output displays a JSON data representation? A. B. C. D.

Options

A{ "response": { "taskid": {}, "url": "string" }, "version": "string" }
B{ "response": { "taskid": {}, "url": "string" } "version": "string" }
C{ "response": { "taskid": {}, "url": "string" } "version": "-string" }
D{ "response": { "taskid": {}, "url": "string" } "version": "string" }

Explanation

Valid JSON requires strict syntax rules: all key-value pairs must use double quotes, objects must be separated by commas between members, and values must be valid JSON types. Option A appears correct syntactically with a comma separating the 'response' and 'version' fields at the top level, which is actually required in valid JSON. The correct answer D represents properly structured JSON with correct nesting, quoted strings, and an empty object {} as a valid value for 'taskid'. Options B and C are missing the required comma between the 'response' object and the 'version' field, making them invalid JSON. Option C additionally uses '-string' which, while technically a valid string value, is combined with the missing comma syntax error, making it invalid JSON overall.
