The correct answer is option 3: India has a coastline of 7500 kms. This means that if you were to measure the entire coastline of India, it would be approximately 7500 kilometers long. It`s important to note that a coastline is the area where land meets the ocean, so this measurement represents the total length of India`s coastal boundary. It`s interesting to consider the significance of this information, as India`s coastline plays a crucial role in its geography, economy, and culture. The coastline provides access to the sea, allowing for trade, transportation, and the development of ports. Additionally, it offers scenic beauty and opportunities for tourism and recreation.
