Open source software freedom – UGC NET Question

Open source software is developed in a collaborative manner, with source code made accessible so that users can inspect, modify and share improvements subject to licence terms. This model encourages innovation and community participation. Examples include Linux distributions and many educational tools. Thus, the definition in the stem corresponds to open source software.

Option A:
Option A, proprietary, software keeps its source code closed and restricts modification, making it the opposite of what is described.

Option B:
Option B is correct because open source software explicitly allows source code access and redistribution, which are central to the definition given.

Option C:
Option C, freeware only, focuses on cost, indicating software available at no monetary charge but not necessarily with open source code.

Option D:
Option D, shareware only, refers to software distributed on a trial basis or requiring payment after a period, again without implying open access to the source code.
