Explanations:The question asks which Indian state has the longest coastal line. To understand this, it is essential to know the geographical layout of the Indian subcontinent and the states that border the sea. India has coastlines along the Arabian Sea to the west and the Bay of Bengal to the east. Among the states listed, Gujarat, Kerala, Karnataka, and West Bengal have coastlines, but their lengths vary significantly.
Gujarat, located in western India, has the longest coastline among the Indian states. It stretches approximately 1,600 kilometers along the Arabian Sea. This extensive coastline is a significant geographical feature of Gujarat and plays a crucial role in the state's economy, particularly in trade, fishing, and tourism. The coastline of Gujarat includes several important ports such as Kandla, Mundra, and Pipavav, which are vital for international trade.
Kerala, another state with a notable coastline, is located in the southwestern part of India. Its coastline is approximately 590 kilometers long, which is significant but not the longest in the country. Kerala's coastline is known for its backwaters, which are a major tourist attraction.
Karnataka, situated in the southwestern part of India, has a coastline of about 320 kilometers along the Arabian Sea. This coastline is shorter than that of Gujarat and is not the longest in the country. Karnataka's coastline includes the city of Mangalore, which is an important port.
West Bengal, located in the eastern part of India, has a coastline along the Bay of Bengal. The coastline of West Bengal is approximately 217 kilometers long, which is much shorter than that of Gujarat. The coastline of West Bengal includes the Sundarbans, a unique mangrove forest and a UNESCO World Heritage site.
Therefore, among the given options, Gujarat has the longest coastline in India, making it the correct answer to the question. Understanding the geographical features of Indian states is crucial for various competitive examinations, particularly those related to geography and general knowledge.
