(D) None of these
🧠 Explanation:
The world’s oldest parliament is the Althing of Iceland, founded in 930 AD at Þingvellir. It is recognized as the first national assembly in history where free men gathered to make laws, settle disputes, and decide on important matters collectively. The Althing played a key role in Icelandic governance, combining legislative, judicial, and social functions in a single forum. Over centuries, it evolved into a modern parliamentary system, yet it retains its historic significance as a symbol of democratic tradition. Studying institutions like the Althing helps understand the origins of representative governance and the evolution of political systems globally.
