Answer:
B) 12%
Explanation:
As we know that the coupon rate and YTM is equal if it is sold at par. If the coupon rate is less than the YTM than the bond is sold at discount and if the coupon rate is more than the YTM than the bond is sold at premium
Since the question is asking about the coupon rate if the bond is sold at premium so the coupon rate would be higher than the YTM.
So, the coupon rate would be 12%
