Explanation: The question is designed to test the geographical knowledge of the cities within the state of Karnataka. Karnataka is a state located in the southern part of India, and it is known for its rich cultural heritage, historical sites, and diverse geography. The cities listed in the options are all well-known urban centers, but they are not all located within the same state.
Bangalore, also known as Bengaluru, is the capital city of Karnataka and is one of the largest and most populous cities in India. It is a major economic and technological hub, often referred to as the "Silicon Valley of India." Kolar is another city in Karnataka, located in the Bangalore Division, and it is known for its gold mines and historical sites. Mysore, also known as Mysuru, is a city in Karnataka that is famous for its palaces, silk industry, and cultural festivals.
Mumbai, on the other hand, is the capital city of the state of Maharashtra, which is located on the western coast of India. It is one of the most populous cities in India and is known for its financial and entertainment industries, particularly Bollywood. Mumbai is not part of Karnataka, making it the odd one out in this list.
To solve such questions, it is important to have a clear understanding of the geographical boundaries of different states in India and the major cities within them. This knowledge helps in identifying which city does not belong to the specified state. In this case, the task was to identify the city that is not located in Karnataka, and Mumbai is the correct answer as it is the capital of Maharashtra, not Karnataka.
