Q. With reference to the history of India, the terms "kulyavapa" and "dronavapa" denote (UPSC Prelims 2020)
Answer: measurement of land
Notes: The correct answer is [A] measurement of land. During the Gupta period and in ancient Bengal, these terms were used to denote units of land measurement based on the quantity of seeds required for sowing.

• Kulyavapa (Statement A – Correct): Derived from the word Kulya (a winnowing basket or a specific measure of grain). It represented an area of land that required one Kulya of seeds to be sown. In modern terms, it is estimated to be roughly equivalent to 12 to 16 acres.
• Dronavapa (Statement A – Correct): Derived from Drona (a smaller grain measure). It represented the area of land where one Drona of seeds was required. One Kulyavapa was typically equal to eight Dronavapas.
• Other Units: Other related terms found in copper plate inscriptions of this era include Adhavapa (a smaller unit) and Pataka.
• Context (Statements B, C, & D – Incorrect): While the Gupta period saw a sophisticated coinage system (like the gold Dinara and silver Rupaka), these specific terms were strictly agricultural and administrative regarding land grants and sales. They do not refer to urban classifications or religious rituals.

These measurements demonstrate that land was not measured by physical dimensions (length and width) alone, but by its productive capacity and the resources needed to cultivate it.
