The correct answer is C. 6.91%.
To calculate the total return to an investor, we need to calculate the capital gain (or loss) plus the coupon payments received.
In this case, the investor purchased the bond for $1,100 and sold it for $1,085, so the capital gain (or loss) is -$15.
The investor also received 9% in coupon payments, which is $99 (9% of $1,100).
When we add the capital gain (or loss) and coupon payments together, we find the total return to be 6.91% ($99 + (-$15) / $1,100).
An investor is any individual or other entity (such as a business or mutual fund) who invests money with the hope of making a profit.
