The place located at the confluence of Alakananda and Pindar rivers is

The confluence of the Alaknanda and Pindar rivers occurs at Karnaprayag (often spelled Karnprayag or Karan Prayag). The Alaknanda river, which originates from the Satopanth Glacier, meets several tributaries at five sacred points known as the Panch Prayag [2]. Specifically, the Pindar river, which flows from the Pindari Glacier, joins the Alaknanda at Karnaprayag [3]. Other confluences include Vishnuprayag (Alaknanda and Dhauliganga), Nandaprayag (Alaknanda and Nandakini), Rudraprayag (Alaknanda and Mandakini), and Devprayag (Alaknanda and Bhagirathi) [3]. Although the option provided is spelled 'Kamaprayag', it is a clear typographical variant of Karnaprayag, which is the established geographical location for this junction [1]. After the final confluence at Devprayag, the river is officially known as the Ganga [4].
