Which of the following is NOT an example of application software?

Application software refers to programs designed to perform specific tasks for users, such as word processing, graphic editing, or web browsing. Microsoft Word, Adobe Photoshop, and Google Chrome all fall into this category as they are designed for specific user functions—creating documents, editing images, and browsing the internet, respectively.

Windows OS, on the other hand, is classified as system software rather than application software. It is an operating system that manages computer hardware and software resources and provides common services for application software. As such, it facilitates the operation of application programs but is not an application itself.
