Step 1: Understanding the Concept:
Indian astronomical verses use 'Bhuta-Sankhya' (word-numerals) to encode numbers into the meter. These rely on synonyms for elements, senses, deities, and standard quantities.
Step 2: Decoding the Mnemonics:
1. Khanagah (A): 'Kha' = 0 (Sky), 'Naga' = 7 (Mountain). Reading right to left (Ankanam vamato gatih): 70. (A matches III).
2. Kha-agnih (B): 'Kha' = 0, 'Agni' = 3 (Fire). Reading right to left: 30. (B matches I).
3. Panchagnih (C): 'Pancha' = 5, 'Agni' = 3. Reading right to left: 35. (C matches IV).
4. Jinah (D): 'Jina' refers to the Tirthankaras or a standard group of 24. In Jyotish, 24 degrees is the maximum declination (Parama-kranti). (D matches II).
Step 3: Verification:
Sequence: A-III, B-I, C-IV, D-II. This matches Option (2).
Step 4: Final Answer:
The word-numerals provide an error-correcting mechanism for maintaining planetary constants in oral tradition.
