Answer: A. interest rates have risen
Step-by-step explanation:
Since the customer buys a Brokered CD for $100,000 and upon eceipt of his next account statement, he sees that there has been a reduction in the market value of the CD to $99,800.
This would occur because there has been an increase in the interest rates. On the other hand, assuming there was a reduction in the interest rate, this will lead to an increase in the market value.
