B. $0
Explanation:
he transaction between Lin and Zee appears to be a conditional sale. The reason being that zee hardware has the right to return the machine if unable to resell it. According to their agreement, should Zee hardware return the machine, its obligation to Lin will be zero.
As per Lin's assessment, and based on their previous transactions, the probability of Zee returning the machine is very high. Lin is sure that Zee hardware will not sell the machine. For this reason, Lin should not record the transactions as a sale.
