I just took the test and that answer was correct

The national bank Hamilton established in 1790 issued a national currency.

Explanation:

In the 1790s, Hamilton established the First Bank of the United States, a former central bank that was established by statutes of the US Congress on February 25, 1791. The purpose of the bank, which was allowed to operate for 20 years, was to address the financial needs of the US federal government, which was then a completely new nation. The bank was first proposed by Secretary of the Treasury Alexander Hamilton, at the First Congress in 1790. The support came primarily from merchants in the northern United States, while representatives from the southern states were highly skeptical about it.
