A properly formatted JSON script is a text-based data format that follows JavaScript object syntax. It is commonly used for transmitting data in web applications.

It also requires proper use of quotes, commas, and braces. Based on the information provided, option C is the correct answer as it is the only option that does not contain a URL, which is not a valid JSON format.
