A:
They are different.
Active Record Pattern defines An object that wraps a row in a database table or view, encapsulates the data access, and adds domain logic on that data.
In the Repository pattern all of the data access is put in a separate class and is accessed via instance methods. To me, just doing this is beneficial, since data access is now encapsulated in a separate class, leaving the business object to get on with business. This should stop the unfortunate mixing of data access and business logic you tend to get with Active Record.
