B. A class cannot implement an interface partially. The modifier 'static' is not valid in interface so there is no possibility for option D

A. eg:
public interface myinterface
{
void a();
void b();
}
public abstract class myclass : myinterface
{
public void a()
{
///do something
}
public abstract void b(); // keep this abstract and then implement it in child class
}
