   Answer: (1) astronomy

   उत्तर: (1) खगोल-विज्ञान

   All three belong to the Kerala tradition of astronomy: Katapayadi is a letters-for-numbers notation used to encode astronomical values, Parahita is the system of planetary computation attributed to Haridatta (7th century), and Drigganita is the observation-corrected system of Parameshvara (15th century). Katapayadi is also used to number Carnatic melakarta ragas, but the three together point to astronomy.
