Explanation: Port Blair, the capital of the Andaman and Nicobar Islands, is a significant port located in the Bay of Bengal. The Andaman and Nicobar Islands are a union territory of India, and they are geographically isolated from the mainland. To maintain essential connectivity, the government has established regular passenger ship services from Port Blair to major ports on the eastern coast of India.
The correct answer is (A) Chennai, Kolkata, and Vishakhapatnam. These cities are all located on the eastern coast of India and have major ports that serve as important gateways for maritime transport. The ship services from Port Blair to these cities are crucial for the movement of people and goods between the Andaman and Nicobar Islands and the mainland.
Chennai, located in the state of Tamil Nadu, is one of the largest ports in India and serves as a major hub for maritime traffic. Kolkata, in the state of West Bengal, is another significant port city that connects the Andaman and Nicobar Islands to the mainland. Vishakhapatnam, in the state of Andhra Pradesh, is also a major port and provides an important link to the islands.
The other options are incorrect because they include cities that are not coastal and do not have ports. Jaipur, Bangalore (Bengaluru), and Delhi are all inland cities and are not connected to Port Blair by ship services. These cities are important for other forms of transportation, such as air and road, but they do not have the maritime infrastructure necessary to provide ship services to the Andaman and Nicobar Islands.
Understanding the connectivity of Port Blair is essential for comprehending the geographical and logistical aspects of the Andaman and Nicobar Islands. This knowledge is particularly relevant for competitive examinations that test geographical and transportation-related concepts in India.
