Explanation: Arunachal Pradesh is a state in the northeastern region of India, known for its diverse landscapes, rich biodiversity, and cultural heritage. It is situated in the eastern Himalayas and shares borders with Bhutan, China, and Myanmar. The state is characterized by its mountainous terrain, dense forests, and numerous rivers, including the Brahmaputra.
Understanding the geographical layout of India is crucial for identifying which states have coastlines and which do not. Coastal states are those that have a direct border with the sea, either the Arabian Sea or the Bay of Bengal. These states often have significant economic activities related to fishing, shipping, and tourism.
Arunachal Pradesh, being an inland state, does not have a coastline. It is located far from the sea, surrounded by other countries and states. This geographical isolation has contributed to the state's unique cultural and ecological characteristics. The state's economy is largely based on agriculture, forestry, and tourism, with a focus on eco-tourism due to its natural beauty and wildlife.
In contrast, Goa, Andhra Pradesh, and Orissa (Odisha) are coastal states. Goa, located on the western coast, is known for its beaches and is a major tourist destination. Andhra Pradesh, situated on the southeastern coast, has a long coastline along the Bay of Bengal and is known for its ports and fishing industry. Orissa (Odisha), also on the southeastern coast, has a significant coastline and is known for its cultural heritage and natural resources.
Therefore, when identifying states without a coastline, it is important to consider their geographical location and the presence or absence of a direct border with the sea. Arunachal Pradesh, being an inland state, does not have a coastline, making it the correct answer in this context.
