Which was not an accomplishment under monroe's presidency?

A) The Louisiana Purchase

Although James Monroe did help negotiate the Louisiana Purchase in 1803, he did it as President Jefferson's special envoy, not during his actual term. The Presidency of Monroe began in 1817. The Missouri Compromise (1820), The "Era of Good Feelings" (1817–1825) and the issuing of the Monroe Doctrine (1823) are all actions closely associated with Monroe's term.
