Which mobile operating system is free and open source?

• A. Web OS
• B. Android
• C. Apple IOS
• D. Symbian OS

Answer: (B)

Open-source software means the source code is published so anyone can view, modify, and redistribute it. Android fits this description because its core is released through the Android Open Source Project, with most of the code under open licenses like Apache 2.0 and the Linux kernel under GPL. This openness lets manufacturers and developers customize the OS and create their own builds, which is why Android is the go-to example of a free and open-source mobile OS. The others are not open in the same way: iOS is a closed, proprietary system; Symbian OS is largely legacy and not maintained as an open-source project; and WebOS isn’t presented as the primary open-source mobile OS in current practice.
