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$],[$Overnight$],[$Parcel$],[$Letter$],[$Freight$]$

Every single package is known to be either ground, $2-$day air, or overnight. In addition, it is either 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 typ Which of the following correctly describe the specialization? $($one or more could be correct$)$

Partial specialization

Cannot determine if it is partial or complete specialization

Inclusive$/$Overlapping specialization

Exclusive$/$Disjoint specialization

Incomplete specialization

Complete specialization
