Match the following chief rivers with their places of origin.RiversA.YamunaB.KrishnaC.GodavariD.MahanadiPlaces1.Sihawa2.Nasik3.Mahabaleshwar4.Yamunotri

1. A

   A-(4), B-(3), C-(2), D-(1)

   Option (a) matches Yamuna with Yamunotri, Krishna with Mahabaleshwar, Godavari with Nasik, and Mahanadi with Sihawa. This is the correct pairing of each major Indian river with its respective place of origin. Therefore, this option represents the accurate geographical mapping.

2. B

   A-(1), B-(2), C-(3), D-(4)

   Option (b) incorrectly pairs Yamuna with Sihawa and other rivers with mismatched locations. These origins do not correspond to the actual geographical sources of the listed rivers. Thus, this choice is completely wrong.

3. C

   A-(4), B-(2), C-(1), D-(3)

   Option (c) interchanges the origin points for Godavari and Mahanadi while keeping others correct. Such swapped pairs make the entire sequence invalid. Consequently, this option cannot be accepted.

4. D

   A-(4), B-(2), C-(3), D-(1)

   Option (d) incorrectly matches Krishna with Nasik and Godavari with Mahabaleshwar. These mispairings violate well-established geographical facts regarding Indian river systems. Hence, this option is incorrect.

Summary. Official key is (a) A-(4), B-(3), C-(2), D-(1). The Yamuna originates from the Yamunotri glacier in the Himalayas, while the Krishna river rises near Mahabaleshwar in the Western Ghats. The Godavari has its source in the Trimbakeshwar range near Nasik, and the Mahanadi originates from the Sihawa uplands in Chhattisgarh. Careful verification of each river's precise source ensures accurate geographical matching. Therefore, option (a) is the only correct choice.
