Explanation
most significant river in early Sikh history. Option A (“Beas”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option B (“Sutlej”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option D (“Chenab”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Therefore the correct option, index and explanation consistently identify Ravi. The Ravi River is associated with Lahore (now in Pakistan) and the early Sikh history. More specifically, the Beas River is associated with the Sikh Guru - Guru Gobind Singh's battles. However, the correct connection is that Guru Nanak Dev Ji was born in Nankana Sahib near the Ravi River, making Ravi the most significant river in early Sikh history.
