Explanation: The Eastern coast of India is a significant geographical feature that includes several states. The states that form the Eastern coast are Tamil Nadu, Andhra Pradesh, Orissa (now Odisha), and West Bengal. These states are crucial for understanding the geographical layout of India, especially in terms of coastal regions and maritime activities.
Tamil Nadu is located in the southern part of the Eastern coast and is known for its rich cultural heritage and significant ports like Chennai. Andhra Pradesh, situated to the north of Tamil Nadu, is also an important state on the Eastern coast, with major cities like Visakhapatnam and Vijayawada. Orissa (Odisha), further north, is known for its beautiful beaches and the famous Jagannath Temple in Puri. West Bengal, located at the northernmost part of the Eastern coast, includes the city of Kolkata and the Sundarbans, a UNESCO World Heritage site.
It is important to note that the Eastern coast is distinct from the Western coast, which includes states like Maharashtra, Goa, and Gujarat. The confusion between the Eastern and Western coasts is a common mistake among students. Additionally, the name change of Orissa to Odisha in 2011 can sometimes lead to confusion, as some students might not be aware of the current name.
The Eastern coast is not only significant for its geographical features but also for its economic importance, as it includes major ports and is a hub for maritime trade and fishing activities. Understanding the states that form the Eastern coast is essential for students preparing for competitive examinations like UPSC, SSC, State PSC, and Bank PO, where questions on Indian geography are common.
In summary, the correct answer is Option C: Tamil Nadu, Andhra Pradesh, Orissa (Odisha), and West Bengal, as these states form the Eastern coast of India.
