Shirosha, Hemavati, Arkavati are the tributaries of which one of the following rivers?

The Hemavati and Arkavati are major left-bank tributaries of the Kaveri (Cauvery) river [c1][t2]. The Kaveri originates at Talakaveri in the Brahmagiri range of the Western Ghats in Karnataka [c1][t8]. Its significant left-bank tributaries include the Harangi, Hemavati, Shimsha, and Arkavati [t2][t4]. The Shimsha river, which joins the Kaveri near Shivanasamudra, is sometimes referred to in regional variations or historical texts with names like Shirosha [c1][t3]. Other notable tributaries of the Kaveri system include the Kabini, Bhavani, Noyyal, Amaravati, and Lakshmanatirtha [c1][t2]. In contrast, the Tungabhadra and Bhima are major tributaries of the Krishna river [c5][t10], while the Tapti (Tapi) is a west-flowing river with distinct tributaries like the Purna and Girna [c4]. Therefore, the listed rivers belong to the Kaveri river system.
