Which statement best reflects the core idea behind free software?

• A. Users should have the freedom to use software.
• B. Users should have the freedom to use, study, modify, and redistribute software.
• C. Software should always be free of charge.
• D. Source code should never be accessible.

Answer: (B)

Free software centers on freedom, not price. It guarantees four essential freedoms: to run the program for any purpose; to study how it works by having access to the source code; to modify it to fit your needs; and to share copies of either the original or your modified version with others. This combination empowers users, promotes transparency, and supports collaboration and security because anyone can inspect, improve, and freely propagate changes.

The statement that best reflects this idea explicitly includes all four freedoms, highlighting both the ability to use and the access to the code with the right to study, modify, and redistribute. Freedom to use alone misses the crucial ability to understand and adapt the software, which underpins trust and improvement. The notion that software must be free of charge conflates price with freedom and can mislead about what makes software truly libre. Finally, asserting that source code should never be accessible directly contradicts the core premise of free software, which relies on access to code to enable study, modification, and redistribution.
