Answer:
The correct answer is B. Free software.
Step-by-step explanation:
Free software is a term used for software that the holder can use, copy, read, modify and distribute with or without modification at will. Software that falls under this category includes software that is not protected by copyright laws or software that is licensed to be used in this way.
Motives for developing free software can be technical, economic or social. What is significant for developers is the desire to develop as producers of programs by learning from other producers. The desire to help others is also a major motive.
