What is the most suitable option for Norm to invest his $15,000, considering his daughter's upcoming college plans and the associated interest rates?

Norm may need the money soon for his daughter’s college expenses, so a four-year CD with a substantial early-withdrawal penalty is too restrictive. The money market account earns 3.5% and ties up the money for only three months at a time, offering a useful balance of return and access. That makes the three-month money market account the best choice.
