Answer: II. premium price
A bond which has a market price higher than its face value is said to be trading on a premium price. Which means that people are willing to pay more to buy the bond.
IV. yield-to-maturity that is less than the coupon rate
This is also correct because a bond sells higher than its face value when the yield to maturity also known as the bonds internal rate of return is lower than the coupon rate, which means that the bond is paying higher coupons than it needs to attract investors, and because of this investors are willing to pay a premium on it.
