The question asks us to identify which of the provided statements about the G20 are not true. We will analyze each statement to determine its accuracy in reference to the G20.

G20 Statement Analysis

G20 Statement (i): Composition and Nature

Statement (i) claims: "G20 is official group of European Union and other 19 countries."

• G20 Composition: The G20 (Group of Twenty) is indeed comprised of 19 individual countries and the European Union (EU). This means it has a total of 20 members (19 countries + 1 European Union). So, the member composition described is factually correct.
• G20 Nature: However, the G20 is an informal forum for international economic cooperation among major economies. It operates without a formal charter, treaty, or permanent secretariat, which distinguishes it from a formal or "official group" in the traditional sense of an international organization. Its decisions are made by consensus, and it serves as a platform for dialogue.

Therefore, because the G20 is an informal forum rather than an "official group," statement (i) is not true.

G20 Statement (ii): Headquarters

Statement (ii) claims: "G20 has its Headquarter in London."

• G20 Headquarters: The G20 does not have a permanent secretariat or a fixed headquarters in London or any other city. The G20 presidency rotates annually among its member countries. The country holding the presidency is responsible for organizing and hosting the G20 summit and related ministerial meetings for that year. This rotating system means there is no need for a permanent base.

Consequently, statement (ii) is definitively not true.

G20 Statement (iii): Presidency Groups and India's Role

Statement (iii) claims: "In reference to groups made for electing President, India is part of Group-2 which has other members as Russia, South Africa and Turkey."

• G20 Presidency Rotation: The G20 operates on a system of a rotating presidency, not by "electing a President" in the sense of a permanent head of the organization. A different member country holds the G20 presidency each year, guiding its agenda and hosting the annual summit.
• Grouping for Presidency Selection: For the purpose of managing this rotation and ensuring regional balance, G20 member countries are divided into five groups. India is indeed placed in Group 2 for this presidency rotation, alongside Russia, South Africa, and Turkey.

However, the phrasing "electing President" is inaccurate. The G20 system involves a rotating "presidency" among member countries, not the election of a single "President." Due to this inaccuracy in the premise of "electing President," statement (iii) is considered not true, despite the correct listing of countries in Group 2 for presidency rotation purposes.

G20 Findings: Summary of Untrue Statements

Based on our detailed analysis of each statement:

• Statement (i) is not true (G20 is an informal forum, not an official group).
• Statement (ii) is not true (G20 does not have a permanent headquarters).
• Statement (iii) is not true (The G20 has a rotating presidency, not an elected President, even though the mentioned group for presidency rotation is accurate).

Therefore, all three statements—(i), (ii), and (iii)—are not true in reference to the G20.

G20 Overview: Concluding Facts

The G20 serves as a vital informal forum for global economic governance, bringing together 19 leading countries and the European Union. Its operational model is characterized by the absence of a permanent headquarters and a system of a rotating presidency, which ensures dynamic leadership and diverse perspectives from its members each year.

The correct option is the one indicating that all three statements are not true.
