Answer / Amit Kumar
In Ruby on Rails, `app/helpers` contains classes used to share helper methods between views. These helpers encapsulate application-specific logic and make it easier to reuse code across multiple views. On the other hand, `app/controllers` stores controller classes that handle requests from users, manage data flow within the application, and determine how the response should be rendered.
