A-1 Farm Equipment agrees to sell Gunther the green tractor on its lot and promises to have the tractor ready for Gunther to pick up on Saturday. On Friday night, however, a truck veers off the nearby highway and smashes into the tractor, destroying it beyond repair. Will A-1 be liable for breach of contract because the tractor is not available on Saturday?

Select one: 

a. No, because a lawsuit would fall outside the statute of limitations for this kind of action.b. Yes, because they had a valid contract.c. No, because the contract is now impossible to perform so the doctrine of impossibility would relieve A-1s duties.d. Yes, because there are other green tractors that A-1 could deliver to Gunther.
