Pure expectations theory: Multi$-$year periods

Dina would like to invest a certain amount of money for three years and considers investing in $(1)$ a one$-$year bond that pays $3$ percent, followed by a two$-$year bond that pays the forward rate, or $(2)$ a three$-$year bond that pays $7$ percent in each of the next three years. Dina is considering the following investment strategies:

Strategy A: Buy a one$-$year bond that pays $3$ percent in year one, then buy a two$-$year bond that pays the two$-$year forward rate in years two and three.

Strategy B: Buy a three$-$year bond that pays $7$ percent in each of the next three years.

If the two$-$year bond purchased one year from now pays $6$ percent annually, Dina will choose $$

The rate on the two$-$year bond purchased one year from now is $7\mathrm{.}790$ percent.

The rate on the two$-$year bond purchased one year from now is $8\mathrm{.}333$ percent.

The rate on the two$-$year bond purchased one year from now is $9\mathrm{.}058$ percent.
