The correct answer is option 1, 35° N. Latitude is a measure of how far north or south a point on the Earth is from the Equator. The northernmost part of India is the state of Jammu and Kashmir, which is located at approximately 35° N latitude. This means that it is 35 degrees north of the Equator. The latitude lines run horizontally around the Earth, with the Equator being 0° latitude and the North Pole being 90° N latitude. So, the northernmost part of India is closer to the Equator compared to the other options given.
