Concept:An entreport is a transit trading port where imported goods are stored and later re-exported to other destinations.
Explanation:The statement describes a port that specialises in receiving and redistributing goods to neighbouring countries.
This is exactly the function of an entreport.
Goods may be imported, kept temporarily, and then shipped out again to nearby nations.
Such a port acts as a trading centre rather than a terminal for passengers or local traffic.
A ferry port mainly handles ferries, passengers, and vehicles.
An outport is a secondary port that assists a larger, main port.
A river port is simply a port located along a river and is not defined by re-exporting goods.
Therefore, the description given in the statement matches an entreport.
