Which of the following cities is known as the “Hydro City of India”?

Appeared in: NORCET 10 Prelims-2026

Explanation

Visakhapatnam is popularly referred to as the 'Hydro City of India'.
This nickname is attributed to its strategic maritime importance, primarily as it serves as the headquarters of the Eastern Naval Command of the Indian Navy.
The city has a deep connection with water-related activities, including a major port and naval base, reinforcing its 'Hydro City' identity.

Option A: Chennai is a major coastal city but is not known as the 'Hydro City'.
Option C: Kochi is a significant port city, but its nickname is different.
Option D: Mumbai is India's largest port city but is not called the 'Hydro City'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nicknames of Indian Cities as background academic context rather than a clinical decision trigger.
This is a general knowledge question and does not pertain to clinical or nursing practice.
Knowing the nicknames of cities is a common component of the general awareness section in various competitive examinations, including those for nursing recruitment.
What if? - If the stem changed one defining clue so that Visakhapatnam no longer matched, reassess the option whose mechanism, classification, or indication now fits the revised presentation.

How to Approach the Question

Identify the core question: The question asks for the specific nickname 'Hydro City of India'.
This is a factual recall question from the domain of general knowledge (Indian geography).
Analyze the options provided: All are major coastal cities, making the choice require specific knowledge.
Recall or deduce the correct association. 'Hydro' relates to water. While all options are coastal, Visakhapatnam's identity is strongly tied to its large naval command headquarters.
Eliminate other options by recalling their more famous nicknames (e.g., Mumbai as the Financial Capital).
