Final answer:
Credit to Accounts Receivable for $980. When the customer makes the payment on March 7, it reduces the amount owed for accounts receivable.
correct option is B.
Step-by-step explanation:
When the customer makes the payment on March 7, it reduces the amount owed for accounts receivable. The terms of 2/10, n/30 indicate that the customer can take a 2% discount if payment is made within 10 days. In this case, the customer did not take the discount, so the full amount of $1,000 minus the discount of $20 ($1,000 x 2%) is credited to Accounts Receivable, resulting in a credit of $980.
