What type of object does the newNullRobot method return?

  1. Null

  2. Robot

  3. NullRobot

  4. NRobot

The correct answer is: Robot

The newNullRobot method returns an object of type Robot. This means that any method calls or properties applied to the returned object can be used with instances of the Robot class. The other options, Null, NullRobot, and NRobot, are not valid object types and would result in an error if used as the return type for the method.
