The correct answer is A. reducing the time it takes to create new objects.
Inheritance is a powerful concept in object-oriented programming that allows you to create new classes based on existing classes. This can save you a lot of time and effort, as you don’t have to write all of the code for the new class from scratch. Instead, you can simply inherit the code from the existing class and then add any new code that is specific to the new class.
For example, let’s say you have a class called Animal. This class would have all of the code that is common to all animals, such as the ability to eat, sleep, and move. You could then create a new class called Dog that inherits from Animal. This would mean that the Dog class would have all of the code from the Animal class, plus any new code that is specific to dogs, such as the ability to bark.
Inheritance can also help you to avoid code duplication. If you have a lot of classes that have similar code, you can inherit from a common base class to avoid having to write the same code multiple times.
Overall, inheritance is a powerful concept that can save you time, effort, and code duplication.
Option B
is not correct because you still have to think about how objects will be used, even if you are using inheritance. You need to make sure that the new class is using the inherited code in a way that is consistent with the original class.Option C is not correct because inheritance does not necessarily reduce the amount of memory required to execute a program. The amount of memory required depends on the size of the classes and the amount of data that is stored in them.
Option D is not correct because inheritance does not enable people who have not studied programming to create useful applications. Inheritance is a complex concept that requires a good understanding of object-oriented programming.
