Which one of the following is an out-port?

Correct option is C

Introduction
An out-port (or outer port) is a port built away from an existing older port to handle larger ships, heavier cargo, or specialized functions that the inner port cannot accommodate due to limitations like depth or space. The Port of Piraeus, which serves as the primary port for the city of Athens, Greece, is geographically separated from the historic center and handles massive international traffic, including ferry services to the islands and cargo. It functions as a classic example of a modern, large-scale port serving an older, interior city.
Information Booster
· Definition: A port located away from the main town or inner harbor, often closer to the open sea.
· Purpose: Built to accommodate larger modern vessels, reduce congestion, and/or handle specialized cargo that cannot reach the older, inland port.
· Location: Piraeus is located 12 km southwest of the center of Athens.
· Significance: Piraeus is the largest port in Greece and one of the busiest in Europe, serving as the main gateway to the Aegean islands and a major hub for container shipping.
· Modernization: Modern out-ports often feature deep water berths, modern container handling facilities, and extensive storage areas.
Additional Points
· Manchester and Duisburg: Both are examples of inland ports (or river ports), connected to the sea via canals or rivers.
· Kolkata: An example of a riverine port (located on the Hooghly River); its main cargo-handling function is increasingly being taken over by the deeper-water Haldia Dock Complex (which acts as a subsidiary/out-port).
