Which of the following pairs of ancient and modern names of rivers is/are correctly matched? 1. Vitasta : Chenab 2. Asikni : Jhelum 3. Parushni : Ravi 4. Yavyavati : Beas

The correct ancient-modern matches of the Sapta-Sindhu rivers are: Vitasta = Jhelum (not Chenab), Asikni = Chenab (not Jhelum), Parushni = Ravi, Vipasa = Beas, Shutudri = Sutlej, and Sindhu = Indus. Yavyavati is generally identified with the Zhob river (or sometimes the Ravi), not the Beas. Therefore, only pair 3 (Parushni : Ravi) is correctly matched. Pairs 1 and 2 swap Jhelum and Chenab, and pair 4 misidentifies Yavyavati.
