Explanations:The Rabindra Setu and Vidyasagar Setu are two important bridges in West Bengal, India. These bridges are significant for their role in connecting the cities of Howrah and Kolkata across the Hooghly River, which is a distributary of the Ganges River.
Rabindra Setu, formerly known as the Howrah Bridge, is a cantilever bridge that spans the Hooghly River. It connects the twin cities of Kolkata and Howrah, serving as a major transportation link between these two important urban centers. The bridge is named after the renowned Bengali poet Rabindranath Tagore, who was the first Indian to receive the Nobel Prize in Literature.
Vidyasagar Setu, also known as the Second Hooghly Bridge, is a cable-stayed bridge that was constructed to ease the traffic congestion on Rabindra Setu. It also connects Kolkata and Howrah, providing an alternative route for vehicular traffic. The bridge is named after Ishwar Chandra Vidyasagar, a 19th-century Bengali polymath who made significant contributions to Bengali literature, education, and social reform.
Both bridges are essential components of the urban infrastructure in West Bengal, facilitating the movement of people and goods between Kolkata and Howrah. They are not only important for transportation but also serve as landmarks and symbols of the region's engineering and architectural achievements.
It is important to note that the cities connected by these bridges are within the state of West Bengal. Calicut, mentioned in option A, is a city in the state of Kerala, which is located in a different part of India. Therefore, the correct answer is that Rabindra Setu and Vidyasagar Setu connect Howrah and Kolkata.
