Concept:India's northernmost point is a geographical landmark, not to be confused with its southernmost point.
Explanation:The northernmost point of India is Indira Col, located in the Karakoram Range at an altitude of 5,764 metres.
Indira Col is on the Siachen Muztagh and has two passes; the eastern one was named in 1912.
Do not mix it up with Indira Point, which is the southernmost point of India, located near Great Nicobar.
Indira Point is also called Pygmalion Point and was renamed in 1985 after Indira Gandhi.
The north-south extent from Indira Col to Kanyakumari is 3,214 km.
Among the given options, only Indira Col is the correct northernmost point. Indira Heights is not an extreme point, and Indira Point is southernmost.
