Answer:
b. A Eurodollar is a U.S. dollar deposited in a bank outside the U.S.
Step-by-step explanation:
A Eurodollar is a bond issued by a foreign company in US dollars instead of heir own domestic currency. Eurodollars are issued and redeemable at the foreign country, no the US. It has nothing to do with money deposited in banks outside of the US, since it refers to bonds, not deposits.
