Match List - I with List - II. List I — Thinkers List II — Text/Subject A.…

Concept: In classical Indian scholarship a thinker is identified with the foundational treatise of one specific discipline — dramaturgy, grammar, medicine or mathematical astronomy. A matching item of this kind is solved by first fixing each name to its discipline, and then to the text that the discipline's own tradition attributes to that name; because the disciplines are mutually exclusive, every name binds to exactly one text.

Application: Taking the four thinkers in turn:

1. Bharatmuni belongs to the tradition of nāṭya — dramaturgy and the performing arts; the foundational treatise of that discipline is the Nāṭyaśāstra, so A pairs with IV.

2. Patanjali the grammarian belongs to vyākaraṇa; his great commentary on Pāṇini's Aṣṭādhyāyī and on Kātyāyana's vārttikas is the Mahābhāṣya, so B pairs with II.

3. Vāgbhata belongs to Āyurveda; he is credited with the Aṣṭāṅgasaṃgraha, the compendium of the eight limbs of medicine, so C pairs with I.

4. Brahmagupta, working around 628 CE, belongs to jyotiṣa and gaṇita; his major work of astronomy and mathematics is the Brahma-sphuṭa-siddhānta, so D pairs with III.

Cross-check: The four disciplines — drama, grammar, medicine and astronomy — are distinct, so the matching must be one-to-one with no text used twice. The table below shows each of the four texts used exactly once, which confirms the assignment.

Result: The correct matching is A-IV, B-II, C-I, D-III.
