01 Which object was used to identify goods in Harappan trade?
Answer and explanation
Correct answer: A. Seal
Explanation: The governing concept is the role of seals in marking or identifying goods. A seal or its impression could be placed on a package or associated with a trader, helping communicate identity, ownership, or responsibility in an exchange. Therefore, option A is correct. A spindle whorl relates to spinning, a furnace to heating or production, and a plough to agriculture; none performs the identifying commercial role described here.
