Answer:
$700 million
Step-by-step explanation:
From a bank's perspective, liabilities are the money it owes to customers. Customer deposits make up a big proposition of a bank's liabilities. Customer deposits held in the bank are liabilities because the money belongs to customers and not the bank.
The deposits of $700 are the liabilities. Reserves are a part of customer deposits that must be retained at the bank's custody at all times. Bonds are trading assets to the bank.
