Answer 1

Correct Answer - Option 1 : Microsoft office

The correct answer is Microsoft office.

• Operating System: As the name implies, the operating system is system software that operates the computer.
• An operating system is the most basic system software, without which other software cannot work.
• The operating system manages other application programs and provides access and security to the users of the system. Some of the popular operating systems are Windows, Linux, Macintosh, Ubuntu, Fedora, Android, iOS, etc.

• Graphical User Interface: Graphical User Interface (GUI) lets users run programs or give instructions to the computer in the form of icons, menus, and other visual options. Icons usually represent files and programs stored on the computer and windows represent running programs that the user has launched through the operating system.
• Touch-based Interface: Today smartphones, tablets, and PCs allow users to interact with the system simply using the touch input. Using the touchscreen, a user provides inputs to the operating system, which is interpreted by the OS as commands like opening an app, closing an app, dialling a number, scrolling across apps, etc. Examples of popular operating systems with touch-based interfaces are Android and iOS. 
• Gesture-based Interface: Some smartphones based on Android and iOS as well as laptops let users interact with the devices using gestures like waving, tilting, eye motion, and shaking. This technology is evolving faster and it has promising potential for application in gaming, medicine, and other areas.

• Note: Microsoft is not an operating system, it is software that includes various components like Microsoft Word, Powerpoint, Notepad, Excel, etc.
• Hence, we conclude that Microsoft is not an operating system.
