What keyword should be used in a class declaration if you do not want to instantiate a class?

Question

Here is the question I received in a recent technical test:

Which of the following keywords is used in a class declaration if you DO NOT want to instantiate the class?

Also, what is the relevance of this in a real situation? (i.e. it is used a lot) (and static was not an option I'd expect to see).

Which of the following keywords is used in a class declaration if you DO NOT want to instantiate the class?
A) null B) void C) private D) empty

Missing.

nulland voidare not valid keywords in the class declaration, is emptynot a keyword, and privatedoes not interfere with creating an instance.

Question about a trick?

I would rather use instatiation instead of declaring. In this case, I would select null, which

MyClass mc=null;
