Question

Are \(x\) and \(y\) integers? Statement (I): Product \(xy\) is an integer.
Statement (II): \(x+y\) is an integer.

• A. Statement (I) alone is sufficient.
• B. Statement (II) alone is sufficient.
• C. Both statements (I) and (II) are sufficient.
• D. Neither statement is sufficient.

Hint:

Whenever a statement seems sufficient, try constructing a counterexample. If one valid example gives integers and another valid example gives non-integers, the statement is not sufficient.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The prompt requires us to evaluate the listed software and pinpoint the one that functions as system software instead of application software.


Step 2: Detailed Explanation:
Computer software is generally divided into two main categories: system software and application software.
System software is built to operate and manage the computer's hardware, serving as the foundation for application software. Operating systems such as Windows, macOS, and Linux fall into this category.
Conversely, application software is created to help users accomplish specific tasks. Programs like Microsoft Word (for documents), Google Chrome (for internet browsing), and Adobe Photoshop (for graphics) are all application software.
Consequently, the Linux Operating System is the sole example of system software in the provided list.


Step 3: Final Answer:
The correct choice is (C).
