PLEASE HELP

In a single Generalization/Specialization of a Package entity, the entities are modeled as follows: Super type entity: [Package] 6 Sub type entities: [Ground], [2-day Air], [Ovemight], [Parce], [Letter], [Freight] Every single package is known to be either ground, 2-day air, or overnight. In addition, it is elther a parcel, letter, or freight. So, For example: a Package could belong to both Ground and Freight sub types; another could belong to 2-day Air and Parcel sub types. Which of the following correctly describe the specialization? (one or more could be correct) Incomplete specialization Cannot determine if it is partial or complete specialization Partial specialization Complete specialization Inclusive/Overlapping specialization Exclustve/Disjoint specialization
