The correct answer is

Microsoft windows

To understand which option is an example of a proprietary system software, let's first define the terms involved:

Understanding Proprietary System Software

Proprietary Software is software that is owned by an individual or a company (usually the one that developed it). Its use is restricted by licenses and the source code is not made publicly available. Users must pay for a license to use proprietary software.

System Software refers to the software designed to operate and control the hardware of a computer, providing a platform for running application software. It includes operating systems, device drivers, utility software, etc.

Analysis of the Options:

  1. Linux: This is an open-source operating system, meaning its source code is freely available and can be modified by anyone. It is not proprietary.
  2. Microsoft Internet Explorer: This is a web browser, which is considered application software rather than system software. While it is proprietary, it does not qualify as system software.
  3. Microsoft Office: This is an application suite, not system software. It is proprietary but doesn't fit the category of system software.
  4. Microsoft Windows: This is a proprietary operating system and thus a perfect example of proprietary system software. Microsoft owns it, and it requires that users purchase a license.

Conclusion:

Based on the definitions and analysis, Microsoft Windows is an example of proprietary system software. It fulfills both criteria: it is an operating system (hence, system software) and is proprietary (owned and licensed by Microsoft).
