Let’s match each organisation with its correct function:
CAC (Codex Alimentarius Commission) – Publishes internationally recognized food standards, guidelines and codes of practice to ensure food safety.
ISO (International Organization for Standardization) – A global non-governmental federation that develops voluntary international standards.
WTO (World Trade Organization) – Established in 1995, it manages international trade agreements and settles trade disputes.
BIS (Bureau of Indian Standards) – Offers voluntary and mandatory certification schemes to ensure product quality in India.
Hence, Option (C) is correct.
