1)D, i think...
2)B, i think... not sure
Answer: C
Explanation:
This is because although the coupon rate is devoid of federal income tax any market discount is taxed as interest income earned. So so if there is a way that they can be taxed without jeopardizing their basic Federal income tax-free status, why not? The discount can be accreted annually and tax paid, or the tax can be paid at maturity or sale date.
The fourth answer is correct (D).
The savings account is an investment that generates little income. To make long-term investments, there are other options that give a better return.
However, this type of account serves so that the money that will be used in the short term has at least some income. In other words, if the investor is sure that he does not need the liquidity of the money, he can apply in bonds, debentures, shares, etc. If the investor has money that needs to be kept liquid to be used soon, the best option is the savings account.
