WTO in its 8th Ministerial conference adopted a decision allowing members to waive the provisions of Article II (most favored-National Treatment) of the GATS to allow the granting of preferential treatment to services and service supplies to which countries?

Correct option is C

The 8th Ministerial Conference of the WTO held in 2011 allowed a waiver of the Most Favored Nation (MFN) provision under GATS (General Agreement on Trade in Services). This decision enabled member countries to grant preferential treatment to Least-Developed Countries (LDCs) for services and service suppliers without extending the same to other members​​.
Information Booster:
· Least-Developed Countries (LDCs): These are nations identified by the UN as facing severe socio-economic development challenges, such as low income, weak human assets, and economic vulnerability.
Additional Knowledge:
· Adjacent Countries: Typically refers to neighboring countries, not specifically covered by this decision.
· Non-Nuclear Countries: No connection exists between nuclear status and GATS provisions.
· SAARC Countries: While SAARC countries include some LDCs, preferential treatment is not exclusive to this group.
