Comprehensive and Detailed Explanation From Exact Extract:
A joint account allows the husband to retain trading authority and includes the right of survivorship, ensuring the assets revert to him if his wife dies. The feedback from the document states:
"The husband would have no financial interest in a client name account, registered in his wife's name only. A nominee account would transfer trading authority to a dealer or third-party administrator. In a tenants in common account, each spouse would have trading authority over his/her portion of the account. Therefore, the husband's best option would be to open a joint account and retain full trading authority. A joint account would also offer the right of survivorship, which is not a feature of a tenants in common account."

A put option is a contract that gives the buyer the right, but not the obligation, to sell a set number of shares of an underlying asset at a set price within a specified time frame. The buyer of a put option expects the price of the underlying asset to fall below the strike price before the expiration date. Therefore, A is the correct answer.

Interest income distribution is a type of income that a mutual fund pays to its investors from the interest earned on its fixed-income investments, such as bonds and mortgages. Interest income distribution is taxed as ordinary income at the investor's top marginal tax rate, which is the highest tax rate that applies to their income bracket. Therefore, B is the correct answer. References: Interest Income and Taxes - Fidelity, Topic No. 403, Interest Received | Internal Revenue Service

The current yield of a bond is the annual interest payment divided by the current market price of the bond.
The annual interest payment is the coupon rate multiplied by the par value of the bond. In this case, the annual interest payment is:
6.75%×10,000=675
The current market price of the bond is $9,200. Therefore, the current yield is:
9200675×100%=7.34%
The current yield is higher than the coupon rate because the bond is selling at a discount, meaning that its market price is lower than its par value. This implies that the bond is offering a higher return than the prevailing market interest rate. However, the current yield does not take into account the capital gain or loss that will occur when the bond matures or is sold. A more accurate measure of the bond's return is the yield to maturity (YTM), which is the annualized rate of return that accounts for both the interest payments and the price change of the bond over its remaining term.
