SDR popularly called-

Currency note
Paper silver
Credit Receipt
Paper Gold

The correct answer is: C. Credit Receipt

SDRs are Special Drawing Rights, an international reserve asset created by the International Monetary Fund

(IMF) in 1969 to supplement the official reserves of member countries. SDRs are not a currency, but rather a potential claim on the freely usable currencies of IMF members. They can be used to settle international payments, and can also be exchanged for currencies of IMF members.

A currency note is a piece of paper that is used as money. It is issued by a government or central bank, and is usually backed by gold or silver.

Paper silver is a type of silver that is stored in paper form. It is not a physical asset, but rather a claim on silver that is held by a bank or other financial institution.

Paper gold is a type of gold that is stored in paper form. It is not a physical asset, but rather a claim on gold that is held by a bank or other financial institution.

SDRs are different from currency notes, paper silver, and paper gold in that they are not a physical asset. They are a potential claim on the freely usable currencies of IMF members. This means that they can be used to settle international payments, and can also be exchanged for currencies of IMF members.
