Answer:
Dr merchandise inventory $250
Cr accounts payable             $250
Explanation:
The appropriate thing to do on the transaction date would be to recognize that $250 is being owed to the supplier from whom the German chocolate was bought by crediting accounts payable with $250 and debiting merchandise inventory with the same amount.
Upon payment on 31 March 2014,the accounts payable amount is reversed by a way of debit and cash account credited accordingly with the $250 to show an outflow of cash from the business.
