Which of the following languages is considered object-oriented?

Python is considered an object-oriented programming language because it supports the principles and paradigms associated with object-oriented design. This includes encapsulation, inheritance, and polymorphism, which are fundamental concepts in object-oriented programming (OOP). In Python, everything is treated as an object, including functions and data types, which allows developers to create classes and instantiate objects easily. The syntax and structure of Python facilitate the implementation of OOP principles, making it a powerful and flexible language for developers who wish to build applications using an object-oriented approach.

Other languages listed, such as C, Fortran, and BASIC, do not fully embrace object-oriented paradigms in the same way Python does. While some of these languages may support certain aspects of OOP through additional libraries or extensions, they were not designed with object-oriented principles as a core focus. This distinction is key in understanding why Python stands out as an object-oriented language in this context.
