Step 1: Understanding Pramanas.
Pramanas are the means of obtaining valid knowledge. Each school of philosophy accepts a different number and type of Pramanas.
Step 2: Pramanas in Sankhya.
Sankhya Philosophy accepts only three Pramanas:
1. Pratyaksha (perception)
2. Anumana (inference)
3. Shabda (verbal testimony, but limited)
In some classical listings, Sankhya emphasizes the first two strongly.
Step 3: Matching with given options.
- A. Pratyaksham = perception = accepted.
- B. Upamanam = comparison = not accepted by Sankhya.
- C. Anumanam = inference = accepted.
- D. Aitihyam = tradition = not accepted in Sankhya.
Step 4: Elimination.
Hence, the two valid Pramanas are A (Pratyaksha) and C (Anumana).
Step 5: Conclusion.
Therefore, Sankhya accepts Pratyaksha and Anumana as valid Pramanas.
