Which one of the following pairs of a river and its tributary is nor correctly matched ?

The pair Narmada: Amaravati is incorrectly matched. The Amaravati River is a significant tributary of the Kaveri (Cauvery) River, originating in the Annamalai Hills and joining the Kaveri in Karur district [1]. In contrast, the Narmada's major tributaries include the Tawa, Hiran, Barna, and Shakkar [1]. The other pairs are correctly matched: the Wainganga is a key tributary of the Godavari, eventually joining the Wardha and Penganga to form the Pranhita [4]. The Bhavani is a major right-bank tributary of the Cauvery [1]. The Bhima is the longest tributary of the Krishna River, rising in the Sahyadri ranges [3]. While an 'Amaravati' stream exists in the Tapi basin, it is not a tributary of the Narmada, making option 3 the correct answer for the mismatch.
