In specialization hierarchies with multiple levels of supertype/subtypes, a lower-level supertype inherits all of the attributes and relationships from all of its upper-level subtype.
A) True
B) False

In the given statement, The level of the greater supertype entity and the level of the smaller subtype entity are put in the order that is specialization hierarchies, It is not the different levels of both of the entities and it cannot inherit the level of the smaller supertype entity but it inherit the level of the smaller subtype entity. So, that's why the following statement is not true.

Answer:

The answer is "Option B".

Explanation:

The specialization hierarchy is the specific characteristic of a super-type object. This hierarchy focused on the top-down approach to identifying subtype of a subtype in lower-level.

It also describes a more specific entity.

This hierarchy provides the “is-a” relationship model, that includes several levels of subtype or supertype, which relates it, that's why this statement is false.

In specialization hierarchies with multiple levels of supertype/subtypes, a lower-level supertype inherits all of the attributes and relationships from all of its upper-level subtype. A) True B) False
