A Correct answer
Explanation

In Rails, every model class inherits from ActiveRecord::Base (or ApplicationRecord in Rails 5+, which itself inherits from ActiveRecord::Base). This provides ORM functionality, database interaction, validations, and associations. ActiveRecord is the core Rails component that connects models to database tables. ActiveModel is for non-database models, and the other options don't exist.
