Complete Step by Step Answer: The Duncan Passage is located between South Andaman and Little Andaman. It joins the Andaman Sea to the Bay of Bengal. It is about 48 kilometres wide. It has Rutland Island of South Andaman district to the north and Little Andaman Island to the south.
a.Afghanistan and India: India shares a short land boundary with Afghanistan in its North. It is only 106 kilometres long. It is a part of the Durand Line which now forms the boundary of Afghanistan and Pakistan. So, it is an incorrect option.

It is often referred to as the Durand Line. The border shared by the countries is heavily inhabited by people of Pashtun ethnicity on both sides. So, it is an incorrect option.
c.South Andaman and Little Andaman: Andaman and Nicobar Islands are an Indian Union Territory located in the Bay of Bengal. They are an archipelago of islands which are separated by many straits and channels. The capital of the Union Territory is Port Blair. The islands are home to the Indigenous Sentinelese people. South Andaman is separated from Little Andaman Island by the Duncan Passage. So, it is the correct option.
d.Shivalik and Karakoram: The Shivalik Hills and the Karakoram ranges are separated by the Great Himalayas in between them, apart from the other smaller mountain ranges falling in between them such as the Pir Panjal and the Ladakh ranges. So, it is an incorrect option.

Note: The Duncan Passage is not to be confused with the 10 degree channel. The Duncan passage separates two parts of the Andaman Island groups, while the ten degree channel separates the Andaman and the Nicobar groups.
