In the following question, names of Indian cities are given. Three of these cities are important seaports located on the coast of India, while one city is an inland state capital that is not a major seaport. Select the city which is different from the other three (odd one out).

Introduction / Context:
This general knowledge question focuses on Indian geography and important port cities. You are asked to distinguish between coastal seaport cities and an inland city. This type of odd one out question tests awareness of major locations in India, especially those relevant to trade, transport, and economic activity.

Given Data / Assumptions:
- The options are Vishakhapatnam, Mumbai, Kochi, Bhubaneshwar, and Chennai.
- Vishakhapatnam, Mumbai, Kochi, and Chennai are significant coastal cities with major seaports used for maritime trade.
- Bhubaneshwar is the capital of Odisha and is located inland, not directly on the seacoast as a primary port city.
- Exactly one city is not a major seaport, and that city is the odd one out.

Concept / Approach:
The key idea is to classify each city by whether it has a major sea harbour and lies on the coastline. Port cities play a crucial role in import and export activities, whereas inland capitals may have administrative importance but not seaport facilities. By remembering which cities are frequently mentioned as ports in school geography and current affairs, we can quickly identify which city in the list does not fit the seaport category.

Step-by-Step Solution:
Step 1: Mumbai is India's leading western coastal metropolis and has one of the busiest ports in the country.Step 2: Kochi is a well known seaport on the south west coast of India in the state of Kerala.Step 3: Vishakhapatnam is a major port city on the eastern coast of India, located in Andhra Pradesh.Step 4: Chennai is an important eastern coastal city in Tamil Nadu with a major seaport.Step 5: Bhubaneshwar, however, is an inland city and the capital of Odisha. It is not itself the main sea harbour of the state; that role is taken by port towns such as Paradip.Step 6: Therefore, Bhubaneshwar is the only city in the list that is not a major seaport city on the coast and is the odd one out.

Verification / Alternative check:
You can verify by recalling maps or common news references. Mumbai, Kochi, Vishakhapatnam, and Chennai are all frequently mentioned in the context of shipping, navy bases, and maritime trade. Bhubaneshwar is instead known for temples, administration, education, and its role as a political capital of Odisha. It is not typically associated with sea harbours in textbooks or current affairs, which confirms that it stands apart from the port cities.

Why Other Options Are Wrong:
Vishakhapatnam, Mumbai, Kochi, and Chennai all qualify as major seaport cities. They have coastal locations and extensive port infrastructure. Because these four share the common feature of being maritime gateways, they form a natural group. None of them can be considered the odd one out when compared with an inland capital like Bhubaneshwar.

Common Pitfalls:
Some students may misremember geographic locations or confuse nearby coastal and inland cities. For example, they may mistakenly think that any large city in a coastal state must be a port. To avoid such errors, it is useful to memorise the names of a few key ports on each coast. When you know which cities are primary harbours, identifying the odd inland city in such questions becomes quick and reliable.

Final Answer:
Bhubaneshwar
