Question

Which of the following is operating system?

• A. MS Word
• B. Ventura
• C. Java
• D. Windows

Hint:

OS manages hardware; applications run on OS.

Answer 1

The Correct Option is D

Step 1: Define what an operating system actually does.
An operating system is the software layer that manages a computer's hardware and resources directly, things like the processor, memory, storage, and input or output devices, and it provides the platform on which other programs run.
Step 2: Check each option against that definition.
MS Word only processes documents, Ventura only handles page layout, and Java is a programming language and runtime platform, none of these manage hardware resources themselves, they all run on top of some other system.
Step 3: Identify the one that fits.
Windows is the software that actually controls the hardware and provides the environment in which Word, Ventura, and Java programs are able to run.
\[ \boxed{\text{Windows}} \]
