The answer, on the point of view of Boster, is A. Debit notes receivable and credit accounts receivable (not payable i think). This is from the point of view of Boster. So to Boster, he will have an accounts receivable by Martin company. So what Martin did is that he offered a promissory note to Boster. This will increase Boster's notes receivable. At the same time, this will also lessen Boster's accounts receivable since this turned into a notes receivable.
