Which of the following reasons explains why Hudson founded New York harbor?

The Hudson founded New York harbor because "he had navigated the area and knew of a waterway".

Explanation:

In 1609 Hudson was selected to sail across northern Russia via the Arctic Ocean to get to the Far East. Hudson traveled in the Half Moon on April 6, a merely 73-ton ship with a crew of eighteen to twenty people. He explored the North American coast and discovered the Delaware Bay a year before the English did, and his ship reached New York's port on September 3, and soon afterwards began climbing the Hudson River to see if it could find a way down that road.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
