Q. Consider the following ancient river names along with their proposed modern equivalents:

1. Sindhu - Indus
2. Vitasta - Chenab
3. Askini - Jhelum
4. Vipasa - Ravi

Which of the above pairs is / are correctly matched?
Answer: Only 1 and 3
Notes: The ancient name "Sindhu" corresponds to the modern "Indus," correctly mentioned in option 1. However, in option 2, "Vitasta," refers to the Jhelum, not Chenab. "Askini" correctly corresponds to the Chenab, as mentioned in option 3. Lastly, "Vipasa" is the ancient name for "Beas," not "Ravi." Therefore, the only correctly matched pairs are "Sindhu - Indus" and "Askini - Jhelum," making option C the correct answer.
