Which river in India flows both east and west of the Amarkantak plateau?

The Johila River also originates here. Option A (“Ganga and Yamuna”) 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 (“Chambal and Betwa”) 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 (“Mahanadi and Tapti”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. The key concept is to match the water body with its basin, type, location and defining feature. Therefore the correct option, index and explanation consistently identify Narmada and Son. The Amarkantak plateau in Madhya Pradesh is the origin point of both the Narmada River (flowing west into the Arabian Sea) and the Son River (flowing east into the Ganga). This unique geographical feature makes Amarkantak a significant place.
