Answer:
c. The price of Bond A will decrease over time, but the price of Bond B will increase over time
Explanation:
Bond A has a higher coupon rate than market thus, investor will accept to purchase the bond for a higher price until the YTM of this bond equals the market rate
Bond B is the opposite, is paying lower thus, will we purchase for less.
As times passes both will get their market value closer to the face value of the bond because, at maturity the bond will pay 1,000.
Making Bond A lower his price while B increases.
