Identify the sea-port in India on the basis of the given characteristics : 1. It is more than a century old port on the west coast of India. 2. It is a natural harbour protected by a breakwater and also by a mole. 3. A deep draft channel of about 14 metres depth permits large vessels to enter the harbour.

Mormugao Port, located in Goa on the west coast of India, perfectly matches the described characteristics:

• Historical Significance: Commissioned in 1885, it is one of India's oldest modern ports, having served for over 135 years.
• Structural Features: It is a natural harbour situated at the mouth of the Zuari River. To ensure year-round operations and protection from the South West Monsoons, the harbour is protected by a specific breakwater and a mole (a massive stone pier).
• Capacity: The port maintains a deep-draft channel (dredged to approximately 14.4 metres), allowing large Capesize vessels to navigate the harbour, primarily for iron ore export.

In contrast, Jawaharlal Nehru Port is a modern port (established 1989), and Deendayal Port (Kandla) is a tidal port. The specific mention of a century-old status combined with a breakwater/mole protection is a classic geographical identifier for Mormugao.
