Show answer & explanation

Correct answer

Django supports Abstract Base Classes, Multi-table Inheritance, and Proxy Models

Explanation

Django supports three types of model inheritance: Abstract Base Classes (no database table), Multi-table Inheritance (each model has its own table with a ForeignKey to parent), and Proxy Models (same table as parent). Abstract inheritance is most common for sharing fields.
