Which of the following is not a type of operating system?

Explanation:
An operating system is system software that coordinates hardware and provides core services for running programs, such as managing memory, scheduling processes, handling I/O, and offering a user interface. Windows, macOS, and Linux fit this role because they are designed to be the foundation on which other software runs. Firefox, on the other hand, is a web browser—an application that runs on top of an operating system to access and render web content. It doesn’t manage hardware or provide low-level services itself; it relies on the OS for those functions. So Firefox is not an operating system.
