The correct answer is Open Source Software.
OSS stands for Open Source Software, which refers to software that is made available to the public with a license that allows anyone to view, modify, and distribute the source code. Open-source software is typically developed collaboratively by a community of developers. Examples of OSS include the Linux operating system, the Firefox browser, and the Apache web server.
Explanation of Other Options:
(B) Original Source Software:
This is not a standard term in the software industry. The term "source software" generally refers to the source code, but "original source" doesn't refer to any widely accepted category of software.
(C) Open System Software:
"Open system software" is not a standard term either. While "open" refers to software with an accessible source code, "system software" typically refers to operating systems or utilities, but the term “open system software” is not commonly used in the context of OSS.
(D) Original System Software:
This option is also incorrect. System software typically refers to the software that manages computer hardware and provides a platform for running application software (such as operating systems). "Original system software" is not a widely recognized term.
Summary:
- The correct full form of OSS is Open Source Software.
- Original Source Software, Open System Software, and Original System Software are not standard terms used in the software industry.
