Answer:
there are no possibilities
Explanation:
A class / subclass relatonship is not going to be possible here.
This is because we have these four caegories namely
1. compact,
2. midsize,
3. full-size, and
4. sport utility
These four categories have no real unique relationship or attributes with an entity type. A minimum of a supertype has atleast one subtype as well as following the total specialization situation.
1) exclusivity of rights to choose the use of the resource
2) exclusivity of rights to the severices of a resource
3) rights to exchange at mutually agreeable terms
