Hmmm, I’m not too sure about that. In the question it states ‘The web
service contains one method named GetFullName that returns an Object named data. The
data object contains two properties named GivenName and Surname.’. I would think that res contains an object named data that has two properties, GivenName and Surname.

The object we are passing to the function in Success: Function(obj); is the data.
So, in this case res itself is the data object no need to call res.data

You can access object properties in two ways:
objectName.propertyName
or
objectName[propertyName]
