Class Inheritance Theoretical Insight

I was asked recently the following question and wasn't sure how well I did answering it so I wanted to see what people's thoughts were on the question:

If you were dealing with a class of apples and a class of bushels. What class would inherit from the other and why?

Let me know your thoughts, thanks.

I don't think either class should derived from the other. Apples and bushel baskets are fundamentally different things. A bushel may contain apples, but there's no IS-A relationship which would suggest inheritance.

Probably the Apple class should derive from a more abstract Fruit class, while Bushel might inherit from some more abstract Container class. You could then specify that a Container contains zero or more instances of Fruit.

Neither. Apples are not bushels and bushels are not apples. Bushels contain apples, so the relationship is one of containment, not inheritance.
