b. $1,000 debit.

c. $500 debit.

d. $1,000 credit

The normal balance of an accounts payable is credit.
So you start with $800-cr
Any debit posting will reduce that normal balance and any credit posting will increase the normal balance.

The $600 debit posting will create a $200 credit balance(800-600)

The $300 credit posting will create a $500 credit balance(300+200)

A. $500 - Credit.
