Exchange under the Barter System fails when:
AMoney is freely available
BThere are too few goods
CThere is no double coincidence of wants
DBoth parties are honest
Answer & Solution
Correct answer: C. There is no double coincidence of wants
1. Per OCR example: "X has got cow and Y has got rice for exchange. X wants rice but Y does not want cow. So trade will not take place."
2. Lack of double coincidence kills the trade.
3. Money solves this by being a universal medium.
