Port Blair-the capital of Andaman and Nicobar Islands, is located in which one of the following islands?

Port Blair, the capital and largest city of the Union Territory of Andaman and Nicobar Islands, is located on the east coast of South Andaman Island [t1][t6]. Geographically, the Andaman archipelago is divided into three main islands: North, Middle, and South Andaman, collectively known as Great Andaman [t2]. South Andaman was chosen as the administrative headquarters due to its naturally protected harbor, which facilitates maritime trade and transportation [t2]. The city serves as the primary gateway to the islands, housing the Veer Savarkar International Airport and significant historical landmarks like the Cellular Jail [t2][t4]. While other islands like North Andaman host the Saddle Peak and Middle Andaman features Mount Diavolo, South Andaman remains the most developed and populated hub of the territory [c1][t2].
