Multiple Choice

Consider the following class hierarchy: public class Vehicle
{
Private String type;
Public Vehicle(String type)
{
This.type = type;
}
Public String displayInfo()
{
Return type;
}
}
Public class LandVehicle extends Vehicle
{
Public LandVehicle(String type)
{
Super(type) ;
}
}
Public class Auto extends LandVehicle
{
Public Auto(String type)
{
Super(type) ;
}
}
You have written a program to use these classes, as shown in the following code snippet:
Public class VehicleTester
{
Public static void main(String[] args)
{
Auto myAuto = new Auto("sedan") ;
System.out.println("MyAuto type = " + ______) ;
}
}
Complete the code in this program snippet to correctly display the auto's type.

• A) myAuto.displayInfo()
• B) myAuto.super.displayInfo()
• C) myAuto.super.super.displayInfo()
• D) This cannot be done unless the Auto class overrides the displayInfo method.
