Statement i: SDRs cannot voluntarily be exchanged among members for currencies

Explanation:
- Special Drawing Rights (SDRs) are international reserve assets created by the International Monetary Fund (IMF).
- SDRs are used as a supplementary international reserve asset, and their value is based on a basket of major currencies including the US dollar, euro, Chinese yuan, Japanese yen, and British pound.
- SDRs are allocated to IMF member countries to supplement their official reserves.
- Member countries can use SDRs to settle international transactions, diversify their reserve holdings, and for other purposes approved by the IMF.
- However, SDRs cannot be voluntarily exchanged among members for currencies.
- This means that a member country cannot simply exchange their SDRs for the currency of another member country.
- The exchange of SDRs for currencies is subject to certain conditions and requires the consent of both the member country and the IMF.
- This condition ensures the stability and integrity of the SDR system and prevents misuse or speculative activities.

Statement ii: US is the largest member of the IMF

Explanation:
- The International Monetary Fund (IMF) is an international organization that aims to promote global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty around the world.
- The IMF has 190 member countries, and each member country holds a certain number of quota shares in the organization.
- The quota shares determine the voting power, financial contribution, and access to IMF resources of each member country.
- The United States has the largest quota and is therefore the largest member of the IMF.
- The US quota currently stands at around 17.46% of the total quota shares, giving it a significant influence on the decision-making processes and policies of the IMF.
- The US also has the largest financial contribution to the IMF, which further strengthens its position as the largest member.

Conclusion:
- Based on the explanations above, Statement i is correct as SDRs cannot be voluntarily exchanged among members for currencies.
- Statement ii is also correct as the US is indeed the largest member of the IMF.
