With reference to the history of India, the terms “kulyavapa” and “dronavapa” denote

Answer: A. KULYAVAPA and DRONAVAPA denote UNITS OF LAND MEASUREMENT in ancient India. KULYAVAPA and DRONAVAPA are TERMS FOR MEASURES OF LAND, particularly common in EASTERN INDIAN INSCRIPTIONS from the Gupta and post-Gupta periods, especially in Bengal and Bihar. ETYMOLOGY: The names refer to the AREA OF LAND IN WHICH A GIVEN QUANTITY OF SEED WOULD BE SOWN (a common ancient mode of measuring agricultural area, since direct survey was rare). The names are derived from the dry measures of grain that they could absorb in sowing. 1. KULYAVAPA: the area of land that could be sown with one KULYA of seed. The kulya was a larger volumetric unit. 2. DRONAVAPA: the area sown with one DRONA of seed. The drona was a smaller measure, typically one sixteenth or one eighth of a kulya in eastern Indian usage. These terms are documented prominently in COPPER-PLATE INSCRIPTIONS of the Gupta period (Damodarpur, Faridpur, Mehar grants) and in Pala-Sena period inscriptions of Bengal. They were used to denote sizes of land grants to brahmanas, monasteries, or temples (brahmadeya and devadana grants), as well as to record sale and purchase transactions. OTHER REGIONAL UNITS were also used: NIVARTANA, BHUMI, ADHAVAPA, etc. In Tamil inscriptions the equivalent units include VELI and MA. Such measures help historians estimate the scale of land grants and the agrarian economy of early medieval India. Why other options are WRONG: (B) Coins of different value (such as karshapana, dinara, satamana, suvarna) are different terminology, not kulyavapa/dronavapa. (C) Classification of urban land would use terms like 'vastu', 'griha', 'vatika'. Not these terms. (D) Religious rituals would be denoted by yajna, vrata, etc. Not land-sowing terms.
