The correct answer is option 4: Kailash range. The river Indus originates from the Kailash range. The Kailash range is located in the western Himalayas and is known for its sacred mountain, Mount Kailash. This mountain is considered holy by various religions including Hinduism, Buddhism, and Jainism. It is believed that the Indus River begins its journey from the Mansarovar Lake, which is located at the base of Mount Kailash. From there, the river flows through the Tibetan Plateau and eventually reaches Pakistan, where it plays a significant role in the country`s agriculture and economy. It is important to note that while the other three options mentioned in the question are all mountain ranges in the region, the Indus River specifically originates from the Kailash range.
