Explanation: Kolkata, the capital city of West Bengal, is renowned for its unique and traditional transport systems, particularly trams and rickshaws. These vehicles are not only functional but also hold significant cultural and historical value.
Trams in Kolkata are a unique feature of the city's transport system. The Kolkata Tramways, established in 1873, is one of the oldest tram systems in the world and the only one in India. The trams run on narrow gauge tracks and are a popular mode of transport, especially in the central parts of the city. They are often referred to as "rolling museums" due to their historical significance and the preservation of many of the original trams.
Rickshaws, on the other hand, are a common sight on the streets of Kolkata. These are manually pulled vehicles that provide a traditional and eco-friendly mode of transport. Rickshaws are particularly popular in areas where trams and other motorized vehicles cannot easily navigate. They are an essential part of the city's transport infrastructure, especially in densely populated areas.
In contrast, Mumbai, another major city in India, has a different transport system. Mumbai is known for its extensive suburban railway network, which is one of the busiest in the world. Auto-rickshaws are also a common mode of transport in Mumbai, but trams are not a significant part of its transport infrastructure.
The misconception that trams and rickshaws are the main transport systems in both Kolkata and Mumbai might arise from a lack of specific knowledge about the transport systems in these cities. While both cities have distinct transport systems, only Kolkata is known for trams and rickshaws as its main transport systems.
In conclusion, the correct answer is (B) Kolkata, as it is the city where trams and rickshaws are the main transport systems, reflecting the unique and traditional transport culture of the city.
