What field represents attributes for an object of a class?

What field represents attributes for an object of a class?

Fields are attributes, there is no master field for all attributes.

In my software/programming homework there is a question asking:

The fields that represent attributes for an object of a class are known as _______.

Ah, that's slightly different wording. If they are asking about the object variables, they are called instance variables, if the question is with regard to attributes of a class itself (attributes which comprise the class itself and all instances of said class) then they are called Class variables.
