Which of the following is a characteristic of Python 3?

Python 3 characteristics are part of Linux+ V8 scripting objectives. One of Python’s most important features is its modular and extensible architecture.

Option B is correct because Python 3 supports extensibility through modules and packages. Python includes a large standard library and allows developers to extend functionality using third-party modules or custom code. This makes Python highly adaptable for automation, system management, and DevOps tasks.

The other options are incorrect. Python is open source, not closed source. Python 3 is not fully backwards compatible with Python 2, which is a major distinction emphasized in Linux+ V8. Python is also not binary compatible with Java.

Linux+ V8 documentation highlights Python’s extensibility as a key reason it is widely used in Linux automation. Therefore, the correct answer is B.
