Consider the following pairs of texts and their subjects: 1. Tilakamanjari : Mathematics 2. Nighantu : Medicine 3. Janakikaran : Logic Which of the pairs given above is/are correctly matched?

The pairs are evaluated as follows: 1. Tilakamanjari is a famous Sanskrit prose romance (kavya) written by Dhanapala in the 11th century, not a mathematical text. 2. Nighantu refers to a category of glossaries or lexicons, particularly in the context of Ayurveda (medicine), such as the Rajanighantu which describes medicinal plants and their properties. It also refers to the Vedic glossary of synonymous words. 3. Janakikaran (Janakiharana) is a celebrated Sanskrit epic poem (Mahakavya) composed by Kumaradasa, based on the Ramayana; it is a work of literature rather than a treatise on logic. Logic in Indian tradition is typically represented by the Nyaya school. Therefore, only pair 2 is correctly matched as Nighantu is fundamentally a medical/botanical glossary in the Ayurvedic tradition.
