Let's match the Dravyas with the corresponding Mahakashayas based on Ayurvedic texts:
- Vasuka, Kusha, Kasa are used in Mutravirechaniya (diuretic properties), thus (A) matches with (IV).
- Shallaki, Shalmali, Shrivesthaka are used in Purishvirajaniya (promotes healthy digestion), so (B) matches with (III).
- Draksha, Pilu, Parushaka are used in Jvarahara (fever
-related conditions). Thus, (C) matches with (I).
- Tumba, Vanjula, Elavaluka are used in Vedanasthapana (pain
-relieving), making (D) match with (II).
Thus, the correct matching is (A)
-(IV), (B)
-(III), (C)
-(I), (D)
-(II).
