An investor evaluates the following three bonds:

Tenor Coupon Price

Bond A $12$ years $5\mathrm{.}5\%93\mathrm{.}24$

Bond B $5$ years $8\mathrm{.}0\%102\mathrm{.}11$

Bond C $12$ years $8\mathrm{.}0\%108\mathrm{.}93$

If the investor forecasts a decrease in rates, determine which of the bonds the investor should purchase and explain the reason for why that is the appropriate bond.
