A1 & 2 only ✓ Correct

C2 & 3 only

D1, 2 & 3

Correct answer: (A) 1 & 2 only

Explanation

Statements 1 and 2 are correct: Moodle and Aarogya Setu are built on open-source foundations.

Statement 3 is wrong because Skype is proprietary software, not open source.

Moodle is an open-source learning management system written in PHP.

The Aarogya Setu app had its source code released to the public as open source.

Skype is owned by Microsoft and its code is closed.

Open-source software lets anyone view, modify and share the source code.
