A. B. C. D.D.
The correct answer is D) Python.
OpenStack is an open-source cloud computing platform that is primarily written in Python, which is used as the core programming language for the project. Python is a high-level, interpreted programming language that is easy to learn and has a simple syntax, making it an excellent choice for rapid prototyping and development.
Python is an interpreted language, which means that it does not need to be compiled, making it ideal for rapid prototyping and testing. It is also a dynamically typed language, which means that variables are not required to have a specific type, making it easier to write and modify code.
Python is used throughout OpenStack to implement the various services and components that make up the platform. For example, the Nova compute service, which is responsible for managing virtual machines, is primarily written in Python, as is the Keystone identity service, which is responsible for authentication and authorization.
In addition to Python, OpenStack also uses other programming languages, including Java and C++, for certain components. However, Python is the primary language used at the core of the OpenStack project, making it the correct answer to the question.
