Answer 1

The correct choice is (c) it is invoked automatically by the JSON.stringify() method

Explanation: A common use of JSON is to exchange data to/from a web server. When sending data to a web server, the data has to be a string. In that case json.strigify() is used to convert a javascript object into a string.
