City analogy: “Kolkata, Mumbai, Mangalore”. Choose from the options the city that is similar to these in the same important geographical way.

Introduction / Context:
This analogy style question lists three Indian cities and asks you to pick another city with a similar key feature. Kolkata, Mumbai, and Mangalore share an important geographical and economic characteristic that differentiates them from many other large Indian cities. General knowledge of Indian geography, especially coastal and port cities, is tested here.

Given Data / Assumptions:

• Given cities: Kolkata, Mumbai, Mangalore. • Options: Hyderabad, Delhi, Cochin, Jaipur. • We assume knowledge that some cities are coastal seaports and others are inland.

Concept / Approach:
Kolkata is a major port city on the eastern side of India, near the Bay of Bengal. Mumbai is a very large port city on the western coastline, facing the Arabian Sea. Mangalore is another coastal city and a significant port on the western coast. All three are seaport cities located on the coast. To maintain the same pattern, the answer must also be a coastal Indian seaport city, not an inland city away from the sea.

Step-by-Step Solution:
Step 1: Identify the common property of Kolkata, Mumbai, and Mangalore. All three cities lie on the coast and have important ports used for maritime trade. Step 2: Analyse each option. Hyderabad is an inland city in the state of Telangana, not directly on the sea coast. Delhi is the national capital located far inland in northern India, not on the coastline. Cochin (also known as Kochi) is a well known seaport city in the state of Kerala on the Arabian Sea. Jaipur is the capital of Rajasthan and is also inland, not a coastal city. Step 3: Cochin alone matches the coastal seaport character of the given three cities.

Verification / Alternative check:
We can list: Kolkata (port on Hooghly river near Bay of Bengal), Mumbai (natural harbour on Arabian Sea), Mangalore (port city and fishing centre on Arabian Sea), Cochin (major port on the Arabian Sea). Hyderabad, Delhi, and Jaipur are not seaports, although they are large cities. Because the question is about similarity, not difference, we select the city sharing the seaport nature.

Why Other Options Are Wrong:
• Hyderabad: Important IT and business hub but not a coastal or port city. • Delhi: National capital but inland, with no seaport, so it lacks the maritime connection. • Jaipur: Historic city in Rajasthan, again located inland and not related to sea trade.

Common Pitfalls:
Some candidates may focus only on the fact that all the given cities are large or famous, which applies to every option. However, the more precise similarity is that they are all coastal port cities. Remember that analogy questions typically use a more specific shared feature rather than a very general one like “big city”. Paying attention to geography for each option leads easily to the correct answer.

Final Answer:
The city that is similar to Kolkata, Mumbai, and Mangalore in being a coastal seaport is Cochin.
