Explanations:The question asks about a port situated at the confluence of the Hugli and Haldi rivers in West Bengal, which can accommodate larger ships that cannot enter the Kolkata port. The correct answer is Haldia, which is a major port located in the Haldia Dock Complex in the state of West Bengal, India.
The Hugli (or Hooghly) River is a distributary of the Ganges River, and it flows through the state of West Bengal. The Haldi River is a tributary of the Hugli River. The confluence of these two rivers is a significant geographical feature that provides a strategic location for the Haldia port. This location allows Haldia to serve as a major port that can handle larger vessels, which cannot navigate the shallower waters of the Hugli River further upstream to reach Kolkata.
Kolkata, the capital city of West Bengal, has its own port, but it is limited in its capacity to handle larger ships due to the depth and navigability of the Hugli River. Therefore, Haldia serves as a crucial port for larger vessels, facilitating trade and commerce in the region.
It is important to understand the geographical context of the rivers and the location of the port to correctly identify Haldia as the answer. The other options, such as Paradip, Vishakapatnam, and Port Blair, are located in different states and do not fit the criteria specified in the question.
