The correct answer is Option C: Application software.
Let's break down why:

* Operating System: This is the core software that manages all the hardware and other software on a computer (like Windows, macOS, or Linux). Microsoft Word needs an operating system to run, so it *isn't* the operating system itself.

* Processing Device: This is a physical component like the CPU (Central Processing Unit) that performs calculations and instructions. Microsoft Word is not a physical device.

* Application Software: This is software designed to perform a specific task for the user. Microsoft Word is designed for creating and editing documents, making it application software.

* Input Device: This is a hardware device that sends information to the computer (like a keyboard or mouse). Microsoft Word is not a physical device that you use to input data in that way.

* System Software: This is software that helps run the computer hardware and operating system, for example, device drivers. While Word relies on system software, it itself is designed for user tasks.

Therefore, because Microsoft Word is software designed for a specific user task (creating documents), it falls into the category of application software.
