correct answer: "D people that deposit money in the bank for safekeeping"
The bank uses people's savings to loan money. They usually keep a fraction of what they have in store in case the person that has the money in the bank ask it back. For example, if $5000 are deposited in the bank, for savings, the bank could lend out $4500 of it.
The taxes charged by banks are used for the bank keeping.
