Which statement is true about open source software?

• A. It requires paid licenses
• B. It cannot be modified by users
• C. It is created for free use by everyone
• D. It is only available on Windows

Answer: (C)

Open source software is defined by making the source code available and granting users the freedom to study, modify, and share it. That openness means people can use it freely and adapt it to their needs, so describing it as created for free use by everyone best fits what open source aims to provide. It doesn’t require paying licenses as a defining rule—many open source licenses allow free use, sometimes with optional paid services or support. The idea that it cannot be modified is incorrect because one of the main rights granted by open source licenses is the ability to modify the code. It’s also not limited to Windows; open source projects run on a variety of platforms, including Linux, macOS, and Windows.
