In ServiceNow Table Inheritance, tables can be categorized as Base, Parent, or Child depending on how they relate to other tables.
Understanding Table Relationships in the Given Scenario:
Task Table:
Base Table: Since it is not extended from any other table, it serves as the foundation for other tables.
Parent Table: Because the Incident table extends from Task, Task acts as a Parent table.
Incident Table:
Parent Table: Because Super Incident extends from Incident, it becomes a Parent to Super Incident.
Child Table: Since it extends from Task, it is a Child table to Task.
Super Incident Table:
Child Table: Because it extends from Incident, it is a Child table.
Not a Parent or Base Table because no other table extends from it.
Final Table Classification:

The Task table is the Base table, not Incident.
E . Super Incident table is a Parent table → ❌ Incorrect
No table extends from Super Incident, so it cannot be a Parent table.
F . Super Incident table is a Base table → ❌ Incorrect
It is extended from Incident, meaning it is not a Base table.
I . Task table is a Child table → ❌ Incorrect
Since no other table extends to Task, it is not a Child table.
