Which of the following is an example of Application Software?

Application software refers to programs designed to perform specific tasks for users. These tasks can range from word processing to data management and more specialized functions.

Excel is a prime example of application software. It is designed specifically for tasks involving spreadsheets, calculations, data analysis, and visualization, making it incredibly useful for individuals and businesses to manage and interpret data effectively.

On the other hand, Windows 10, Linux, and OS X are examples of operating systems. These systems provide a platform for application software to run and manage hardware resources; they are not designed for specific tasks like Excel. Thus, the focus of each choice differentiates Excel as the correct answer, as it directly aligns with the characterization of application software.
