I think aside form A and C, B is also correct. Starting from Java 9, Interface can have private method, which could be marked as final.
The code below compiles correctly in Java11 for me.
interface MyInterface {
private final void aPrivateMethod() {}
}
correction:
B is NOT correct. final is not allowed for interface private method
A, C)
