Answer & ExplanationAnswer: [D]
Pratipada-Panchika, written by Bhattasvamin, is a commentary on the Arthashastra. It provides an extensive and detailed explanation of the concepts, principles, and teachings found in the original text of the Arthashastra attributed to Chanakya (Kautilya) or Vishnu Gupta.
The Aparajitaprccha of Bhuvanadeva, Samaranganasutradhara of Bhojadeva, and Prabandhachintamani of Merutunga are not commentaries on the Arthashastra.
Therefore, the correct answer is option D. Pratipada-Panchika of Bhattasvamin is a commentary on the Arthashastra.
