Answer:
B) reserves lost by any particular bank will be gained by some other bank.
Step-by-step explanation:
Banks "create" money when they make loans or buy securities from private parties. This money creation is the result of the money multiplier = 1 / reserve ratio.
This money creation process is not affected by which specific bank may hold the deposits, since money withdrawn from a bank will end up in another bank. The money multiplier applies to the whole banking system, not just an individual bank or group of banks.
