Why C# Not support multiple inheritance

Ambiguity issue that's why c# not support multiple inheritance.

   Example:

1. Assume that class A is having a method fun(). class B and class C derives from class A.
2. And both the classes B and C, overrides method fun().
3. Now assume that class D inherits both class B, and C. (just Assumption)
4. Create object for class D.
5. D d = new D();
6. and try to access d.fun(); => will it call class B's fun() or class C's fun()?

This is the ambiguity existing in diamond problem.
