The longest carbon chain has six carbons and contains a double bond between carbons 2 and 3. As there is an amino group attached to carbon 1, the name of the compound should start with "amino." Next, we need to specify the location of the double bond. Since the amino group has priority over the double bond, we number the chain in such a way that the amino group gets the lowest possible number (i.e., carbon 1). Therefore, the double bond is between carbons 2 and 3. Finally, we need to specify the configuration of the double bond. Since the substituent attached to carbon 2 has a higher atomic number (i.e., carbon) than the substituent attached to carbon 3 (i.e., hydrogen), the double bond has an E-configuration. Therefore, the correct IUPAC name is (E)-4-hexen-1-amine.
