Answer:
B) Accounts receivable 8,000; Sales 8,000
Explanation:
As the math does not entail which inventory methods to be used, I assume it to be a periodic inventory system.
In the periodic inventory system, the credit sales do not follow any rules irrespective of gross methods or net methods.
Option A is incorrect as that option deducts the discount, but did not have the discount entry.
Option C is incorrect as that option provides the payment date related journal.
Option D is wrong due to the same problem.
Option B is the current answer;
Accounts receivable 8,000; Sales 8,000. As sales are on credits, it should have accounts receivables.
