1.      Market rates are currently 5%. A $1,000 par corporate bond carries a coupon rate of 6%, pays coupons semiannually, and has ten coupon payments remaining to maturity. There are 90 days between settlement and the next coupon payment. Which of the following is closest to the dirty and clean prices of the bond？
　　A.     $1,043.76, $1,013.76
　　B.     $1,043.76, $1,028.76
　　C.     $1,056.73, $1,041.73
