Option for specifying that arrays and dictionaries are created as mutable objects

When creating a JSON object, we’ve passed in 0 or nil for the options parameter of

NSJSONSerialization.JSONObjectWithData(data: options: error:) The option for specifying that arrays and dictionaries are created as mutable objects are . Hint: Check the documentation

I did, if you look here: https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSJSONSerialization_Class/index.html#//apple_ref/occ/clm/NSJSONSerialization/JSONObjectWithData:options:error: it says it's of type NSJSONReadingOptions when you click through, under JSONObjectWithData. A constant that reads: "Specifies that arrays and dictionaries are created as mutable objects." is MutableContainers, but MutableContainers doesn't work in the quiz. Any help would be great, thank you.
