Option B (open source license) is the correct choice.
Explanation:
An open-source license permits the distribution of a commercial product in only certain contexts, or through several forms of research collaborations or advancement.
This license requires a development's source code to have been usable or visible, used by third-party companies, or edited or tampered with by programmer community leaders.
The latter options offered are not relevant to the scenario presented. So the solution here was the right one.
