The correct answer is C. Diamond Harbour is not typically classified as a major commercial seaport like the others listed.
– Paradeep is a major seaport located in Odisha.
– Haldia is a major port and industrial complex on the Hooghly River, serving as a port for West Bengal. It is part of the Kolkata Port Trust.
– Dhamra is a major deep-water private port located in Odisha.
– Diamond Harbour is a town on the Hooghly River downstream from Kolkata. While it has some historical significance and limited port-related activities, it is primarily known as a tourist spot and fishing harbour, and not a major commercial sea port in the same league as Paradeep, Haldia, or Dhamra.
India has a coastline of over 7,500 km with numerous major, intermediate, and minor ports handling a vast volume of cargo traffic. The classification of ports depends on factors like capacity, traffic volume, and administrative control.
