Explanation: Mumbai, the capital city of Maharashtra, is famously known as the "City of Seven Islands." This nickname is deeply rooted in the city's historical and geographical development. Originally, Mumbai was not a single landmass but a collection of seven islands: Colaba, Old Woman's Island (now merged with Colaba), Bombay Island (which included several smaller islands such as Mazagaon, Worli, Sion, Dharavi, and Mahim), Parel, Matunga-Mumbai, and Mahim.
The formation of these islands dates back to the prehistoric era when the region was part of the Arabian Sea. Over time, due to geological processes and human intervention, these islands were connected through land reclamation projects. The process of land reclamation began in the 17th century under Portuguese rule and continued under British colonial administration. The most significant reclamation projects took place in the 19th and 20th centuries, which transformed the seven islands into a single, contiguous landmass.
The historical significance of the seven islands is not just geographical but also cultural and economic. Each island had its own unique characteristics and played a role in the development of the city. For instance, Bombay Island, the largest of the seven, was the center of trade and commerce, while Colaba and Mazagaon were important for their ports and shipbuilding industries.
Understanding the concept of the "City of Seven Islands" is crucial for comprehending the historical and geographical development of Mumbai. It highlights the city's unique formation and the significant role of land reclamation in shaping its modern landscape. This nickname also reflects the city's resilience and adaptability, as it has transformed from a cluster of small islands into one of the largest and most populous cities in India.
In summary, the correct answer is (D) City of Seven Islands, as it accurately represents the historical and geographical foundation of Mumbai. This nickname is not just a title but a reflection of the city's rich history and its transformation over centuries.
