Correct answer: A. Human welfare and sustainable development
Explanation: The direct answer is option A, human welfare and sustainable development. FAO works on food, agriculture, nutrition, hunger reduction and food security. These areas improve people’s health and living conditions, while sustainable farming protects soil, water and future food supplies. The reasoning is: secure food supports healthy people; healthy people support development; sustainable methods help future generations too. Therefore FAO’s work strengthens the wider development and human-welfare agenda. Option A is correct. Option B, veto power, is a constitutional power of certain members in the Security Council, not FAO’s purpose. Option C, permanent membership, concerns the structure of the Security Council. Option D, court location, concerns an administrative detail of a judicial institution. Memory cue: food security is a development issue, not a power or courtroom issue.
