Option (a) is correct: Only one organization from the list — the United Nations High Commissioner for Refugees (UNHCR) — has been awarded the Nobel Peace Prize twice. It received the prestigious honour first in 1954 and again in 1981 for its pioneering global work in protecting and assisting millions of refugees worldwide.
Option (b) is not correct: This option would imply two organizations won it twice. However, the World Food Programme (WFP) has won the Nobel Peace Prize only once, in 2020, for its extensive efforts to combat hunger and prevent the use of food as a weapon of war and conflict.
Option (c) is not correct: This option would imply three organizations won it twice. However, the United Nations Children's Fund (UNICEF) has been awarded the Nobel Peace Prize only once, in 1965, for its outstanding contribution to strengthening international solidarity and protecting vulnerable children globally.
Option (d) is not correct: This option would imply all four organizations won it twice. However, the International Labour Organisation (ILO) has won the Nobel Peace Prize only once, in 1969, on the occasion of its 50th anniversary for its work in creating international labour standards and promoting social justice.
