Answer:
d. Rewards for using your debit card
Step-by-step explanation:
A "debit card" allows a person to withdraw his funds from his checking account, not from his savings account. It is the checking account that usually offers debit cards.
A "savings account" allows a person to do "online banking." Some banks are purely online and they offer "low or no monthly fee." Depositing money to your savings account provides a competitive interest rate, which is dependent on the amount of money you are putting away.
