Which river is called the 'Dead River' because it does not reach the sea?

ancient Saraswati River mentioned in the Vedas. Option A (“Luni”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option C (“Banas”) 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 (“Rupen”) 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 Ghaggar. The Ghaggar River is often called the 'Dead River' because it eventually loses itself in the Thar Desert and does not reach any sea. The Ghaggar-Hakra river system is identified by many historians and geographers as the course of the ancient Saraswati River mentioned in the Vedas.
