Answer: e. 0.20
Step-by-step explanation:
The Reserve Requirement is a reserve that the central bank of a country requires that Banks hold in case people started making sudden withdrawals. This way the bank is not in danger of being unable to meet those demands.
The Reserve Requirement is a ratio to the Deposits in the bank by the public.

The Required Reserves totals $20 million.
This means that the Required Reserves are,
= 20 million / 100 million
= 0.20
