Step 1: Matching Stratigraphic Units with Corresponding Archean Cratons
- P. Bababudan Group: This stratigraphic unit is associated with the Western Dharwar Craton (Group II: 2).
- Q. Banded Gneissic Complex-I: This unit is associated with the Aravalli Craton (Group II: 3).
- R. Bonai Granite: This granite is part of the Singhbhum Craton (Group II: 4).
- S. Kolar Group: The Kolar Group is associated with the Eastern Dharwar Craton (Group II: 1).
Step 2: Arranging the Matches
Based on the correct associations:
\[ \mathbf{P = 2, \quad Q = 3, \quad R = 4, \quad S = 1} \]
Final Answer:
Hence, the correct option is: (A).
