Ricardo is talking to his parents about saving for retirement. Which of the following is NOT a good way to save for retirement, and why?

A. Investing in a money market account, because the ability to write checks is
heavily restricted

B. Opening an IRA, because too many types of assets can go into this account

C. Putting money in a 401K account, because the tax on the money is merely
deferred, not eliminated

D. Waiting until one is older, because there will be less time for money to accumulate
