Explanation:

• The World Food Programme (WFP) was established in 1961 by the Food and Agriculture Organisation (FAO) and the United Nations General Assembly (UNGA) and became a full-fledged UN programme in 1965. Its headquarter is in Rome, Italy.
• WFP focuses on emergency assistance as well as rehabilitation and development aid. Two-thirds of its work is in conflict-affected countries, where people are three times more likely to be undernourished than elsewhere.
• The 2020 Nobel Peace Prize has been awarded to the World Food Programme (WFP), a United Nations (UN) agency, for its efforts to combat hunger, bettering conditions for peace in conflict-affected areas and preventing the use of hunger as a weapon of war and conflict.

Hence only statements 2&3 are correct.
