HQ of Red cross at

The correct answer is Geneva. The International Committee of the Red Cross (ICRC) has its headquarters in Geneva, Switzerland. Founded in 1863 by Henry Dunant, the ICRC is a humanitarian organization that operates globally to protect and assist victims of armed conflict and violence. Its headquarters in Geneva serves as the central coordination hub for its worldwide operations, including emergency response, humanitarian law advocacy, and diplomatic engagement with states. Geneva is also the seat of many other international organizations, including the United Nations Office at Geneva, which makes it a natural center for international diplomacy. Davos is known for the World Economic Forum, New York hosts the UN Headquarters, and Vienna hosts several UN agencies, but none are the location of the ICRC's main headquarters. Therefore, Geneva is the correct answer.
