Which of the following is not an advantage of credit cards?

a. ability to make remote purchases

b. tax advantage

c. accepted by most retail establishments

d. record keeping

You can use a credit card to make purchases online, so a. ability to make remote purchases is correct.

You can also keep a record of what you buy - also online. (option d) is correct)

However, it does not change anything about the taxes you pay - there is no reason to lower the taxes for a credit card! So the correct answer is b).
