c) Each class should represent no more than three specific concepts.

d) Each class should represent multiple concepts only if they are closely related.

Explanation / Answer

Q1-(d) Each class should represent a single concept or object from the problem domain because A class is a template for creating

               objects. It is a grouping of object-oriented constructs.

Q2. b) A function is defined as part of a class definition is a wrong choice because a method is a part of class definition instead of   

           class.

Q3 b) Use a method provided by the ShoppingList class because we can access private variables using methods.

Q4.c) x = Fruit() Because this is the way to create a object in Python

Q5.c) getColor getColor is the method name
