Answer #1

The correct match as per definition is:

Disjoint subtype means that each row in supertype may exist in only 1 subtype

Subtype discriminator specifies which subtype has matching row for each supertype row

Total completeness allows for generalisation

Overlapping means that each row in supertype may exist in more than 1 subtype
