Answer 1

I have no idea where the answers break, but this one is the right answer:

any software whose source code is made available free for any third party to review and modify.

Step-by-step explanation:

Open source means the application's code is available for the public to see and use. Anyone can take the code, modifying it accordingly, and distribute it without infringing on the rights of the original developer as the application is open to anyone.
