The answers in brief:

1) Most of them.
2) Because without it we can't override methods.
3) Can can provide working methods and properties.
4) Personally, with very long and complex function names...

And I do realize that these answers aren't a lot of help to you, unless you already understand the answers, and that any interviewer is going to want you to say a heck of a lot more than this.

We can't get you though an interview. These four questions are very unlikely to come up in an interview again, unless you wear a false moustache and apply for the same job under a different name. If you do not know the answers to these questions yourself, then you need to go back to the basics of C# and learn how it works properly - because next time the questions will be on very different parts of the OOPS concept.

Sorry, but that is the way the world works.
