An analyst on the fixed-income desk at Bank PNMS has been asked to complete the construction of a zero-coupon bond price tree that was started by another team member. The analyst is given an interest rate tree of semi-annual spot interest rates quoted on an annualized basis, and the partially completed price tree, both with semi-annual time steps, as shown below (time t in years and price P in USD):

t = 0          t = 0.5         t = 1

               4.65%           5.10%

4.20%       0.72     4.20%

            0.28    3.75%           3.30%

t = 0          t = 0.5         t = 1         t = 1.5

               P(1,1)          975.13        1000

937.49     0.72     q

                   1-q         979.43        1000

             0.28     P(1,0)        983.77        1000

t = 0          t = 0.5         t = 1

               4.65%           5.10%

4.20%       0.72     4.20%

            0.28    3.75%           3.30%

t = 0          t = 0.5         t = 1         t = 1.5

               P(1,1)          975.13        1000

937.49     0.72     q

                   1-q         979.43        1000

             0.28     P(1,0)        983.77        1000

When completing the price tree, which of the following is a correct estimate of price P(1,1)?
