Which one of the following pairs of rivers and tributaries is not correctly matched ?

The pair Ganga: Penganga is incorrectly matched. The Penganga is a major tributary of the Godavari river, not the Ganga [4]. It rises in the Ajanta ranges of Maharashtra and eventually joins the Wardha river to form the Pranhita, which then flows into the Godavari [5]. In contrast, the major tributaries of the Ganga include the Yamuna, Ghaghara, Gandak, Kosi, and Son. The other pairs are correctly matched: the Indravati is a significant left-bank tributary of the Godavari [2]; the Bhima is one of the principal tributaries of the Krishna river, originating near Mahabaleshwar [3]; and the Sukri is a known tributary of the Luni river, which is the primary river system in the arid regions of Rajasthan [1].
