What type of software license allows users to modify the code as they see fit?

The option indicating an open source software license is correct because this type of license explicitly allows users not only to use the software but also to view, modify, and distribute the source code. Open source licenses encourage collaboration and sharing within a community, enabling developers to enhance the software and tailor it to better meet their needs.

This flexibility is fundamental to open source software as it promotes innovation, customization, and the ability to fix bugs or implement new features based on user feedback. Many successful projects like the Linux operating system and the Apache web server operate under open source licenses, illustrating the benefits of communal contribution to software development.

In contrast, proprietary software licenses restrict access to the source code and limit users to only utilizing the software as provided, without modification. Freeware refers to software that is available at no cost but typically does not permit modification of the code. Subscription licenses involve paying for the software on a recurring basis, and they also do not grant users the rights to modify the source code.
