The correct answer is: B. for exchange to occur, each seller must have a product that some buyer wants.
The coincidence-of-wants problem refers to a potential problem individuals might face when conducting a barter trade. In a barter trade system, one individual buys something from another individual by giving him or her another thing in return.

This refers to 'coincidence of wants'.
