Which is an example of software?

The correct answer is Microsoft Word because it is an application software used for word processing tasks. Software refers to the programs and operating information that run on computers and other devices, enabling them to perform specific tasks. Microsoft Word allows users to create, edit, format, and print documents, making it a prime example of software.

In contrast, the other options represent hardware components, which are the physical parts of a computer system. A printer is a device used for producing hard copies of documents, a monitor displays visual output from a computer, and a mouse is an input device that allows user interaction with the computer. None of these perform functions like software does; they require software to operate and offer functionality.
