Creating a new Json object and then converting it to a string? That seems overly complicated. I'll stick with the simple json_encode() method.

Option B looks like it might be a custom function, but I'm not familiar with it. I'll go with the built-in json_encode() function.

The correct answer is A. json_encode() is the standard PHP function to convert a value to JSON.

I'm not sure, but I think B) $string = Json::encode($value); could also be a valid option.
