Correct Answer "E".
Because Fun1() in MyClass is Void Fun1() and should be Fun2 also Void IMyInterface.fun2().
And no need to write public because public is by default.
Output:
interface IMyInterface
{
void fun1();
void fun2();
}
class MyClass : IMyInterface
{
void IMyInterface.fun1()
{ }
void IMyInterface.fun2()
{ }
Because Fun1() in MyClass is Void Fun1() and should be Fun2 also Void IMyInterface.fun2().
And no need to write public because public is by default.
Output:
interface IMyInterface
{
void fun1();
void fun2();
}
class MyClass : IMyInterface
{
void IMyInterface.fun1()
{ }
void IMyInterface.fun2()
{ }

Explicit implementation of interface may not be needed in this case.
Public void fun1 () { } // This will solve the problem.
So, answer E isn't mandatory!
Public void fun1 () { } // This will solve the problem.
So, answer E isn't mandatory!

void fun1() must be public.

@All. As per my knowledge;
1) You can't use Access Modifiers while explicit implementation of interfaces in the Derived Class.
2) All methods in interface derived class should have either implicit or explicit implementation of interfaces, you can't have a mixture of them.

Interface can be implemented explicitly using <InterfaceName>. <MemberName>.
