An interface can contain properties, methods and events.

The  keyword  must implement forces  implementation  of an interface.

Interfaces can be overloaded.

Interfaces can be implemented by a class or a struct.

Enhanced implementations of an interface can be developed without breaking existing code.

Which of the following statements is correct about the C#.NET code snippet given below?

interface IMyInterface 
{
    void fun1(); 
    void fun2();
}
class MyClass: IMyInterface
{ 
    private int i; 
    void IMyInterface.fun1()
    { 
        // Some code
    } 
}

                                
A.Class MyClass is an abstract class.
B.Class MyClass cannot contain instance data.
C.Class MyClass fully implements the interface IMyInterface.
D.Interface IMyInterface should be inherited from the Object class.
E.The compiler will report an error since the interface IMyInterface is only partially implemented.
