Answer: A put if the issuer's rating changes.

## Explanation **Correct Answer: B - A put if the issuer's rating changes.** ### Why Option B is Correct: 1. **Embedded options granted to bondholders** are rights that benefit the bondholder, not the issuer. 2. **A put option** gives bondholders the right to sell the bond back to the issuer at a predetermined price before maturity. 3. **When triggered by a rating change**, this put option protects bondholders from credit deterioration by allowing them to exit the investment. 4. This is a classic example of a bondholder-friendly embedded option. ### Why Other Options are Incorrect: **Option A - A prepayment option:** - This is an **issuer's option** (call option) that benefits the issuer, not bondholders. - Issuers can prepay bonds when interest rates fall, which harms bondholders who lose higher-yielding investments. **Option C - An increasing sinking fund provision:** - This is a **mandatory redemption schedule** that requires the issuer to retire a portion of the debt over time. - While it provides some protection through regular principal repayment, it's not an "option" granted to bondholders. - Sinking funds benefit bondholders by reducing credit risk, but they don't give bondholders discretionary rights. ### Key Concepts: - **Embedded options for bondholders**: Put options, conversion options (convertible bonds), extendible options - **Embedded options for issuers**: Call options, prepayment options, acceleration options - The distinction is crucial: bondholder options provide rights to the investor, while issuer options provide rights to the borrower.
