C...>>>>>longer maturity plus lower coupon (if possible zero coupon) because you expect price decline. You know bond price will go up. In this case, you want bonds with the maximum interest rate sensitivity so that you will enjoy the largest price changes (capital gain) from the change in the interest rate.
You will act in reverse (shorter maturity + higher coupon) if it was a forecast interest increase. This combination will give you minimal price volatility for change in the interest rate.

Thanks.
