The Ghaghara is part of the Himalayan river system and joins the Ganga basin. It rises in the Himalayan region and flows through the northern plains before joining the Ganga. Because of its size and drainage contribution, it is described as a major Himalayan tributary of the Ganga. This is the geographical feature asked about in the question.

Therefore option C is correct. The other choices describe unrelated features: a west-flowing lava river is not the identity of the Ghaghara, a salt lake is a water body rather than this river’s relationship, and the river does not flow only in Kerala. Remembering Ghaghara along with other important Himalayan tributaries such as Gandak and Kosi can help distinguish the Ganga drainage system.
