Explanation: In the context of Indian geography, sea ports are crucial for maritime trade and are typically located along the coastlines of a country. India, being a large country with extensive coastlines on both the west and east, has numerous sea ports that facilitate international and domestic trade.
Mumbai, located on the west coast of India, is one of the most significant sea ports in the country. It is a major commercial and financial hub and has a port that handles a substantial amount of cargo and passenger traffic. The port of Mumbai is vital for the economic activities of the city and the surrounding regions.
Vishakhapatnam, situated on the east coast of India, is another important sea port. It is a major port for the state of Andhra Pradesh and plays a crucial role in the economic development of the region. The port of Vishakhapatnam is known for its strategic location and handles both cargo and passenger traffic.
Paradeep, also located on the east coast of India, is a significant sea port for the state of Odisha. It is an important port for trade and commerce, facilitating the movement of goods and materials to and from the region. The port of Paradeep is strategically located and is a key player in the economic activities of the state.
Delhi, on the other hand, is an inland city located in the northern part of India. It is the capital of the country and is known for its historical and political significance. Being far from the coastlines, Delhi does not have a sea port. The city's economic activities are primarily centered around services, trade, and commerce, but it does not have the maritime infrastructure that coastal cities possess.
In summary, the question tests the understanding of which cities in India have sea ports and which do not. Mumbai, Vishakhapatnam, and Paradeep are all coastal cities with significant sea ports, while Delhi is an inland city without a sea port. Therefore, the correct answer is (D) Delhi.
