Concept:The main representative body of the United Nations is the organ where all member states are represented.
Explanation:The UN has six principal organs.
The General Assembly is the main representative body because every member state has an equal vote.
It discusses and makes recommendations on international issues.
The Security Council is not fully representative because only 15 members sit on it.
The Trusteeship Council is largely inactive.
The Secretariat is an administrative organ, not a representative assembly.
Therefore, the General Assembly is the correct answer.
Answer:B. General Assembly
