Which of the following is not a function of Development Banks?

The option that is not a function of Development Banks is "Issue currency notes". Development banks are financial institutions that specialize in providing long-term financing for projects that promote economic development. They are typically established and funded by governments or international organizations. The main functions of development banks include providing long-term loans for investment in key sectors of the economy, such as infrastructure, industry, and agriculture, and providing technical assistance and advice to investors. They also invest directly in key sectors of the economy to help stimulate growth and development. Additionally, they may undertake priority projects of governments that are deemed essential for economic development. However, issuing currency notes is not a function of development banks. That is typically the role of central banks, which are responsible for monetary policy and the issuance of currency in a country.
