How do you create a virtual environment in Python?

Creating a virtual environment in Python is an essential practice for managing dependencies and ensuring that projects can operate in isolated spaces without interfering with one another. The correct command is "python -m venv env_name."

In this command, "python" invokes the Python interpreter, "-m venv" tells Python to run the "venv" module, which is responsible for creating virtual environments, and "env_name" is the name you want to give to the virtual environment you are creating. This allows for easy activation and management of dependencies specific to that environment, providing a clean installation of libraries without mixing them with system-wide packages or other projects' dependencies.

Other command options provided do not conform to the standard ways of creating a virtual environment in Python, which is why they are not suitable. Understanding the use of the "venv" module is critical for effective Python project management and isolation of package versions.
