Consider a Two-Factor HJM Model Where the Initial Forward Curve $$T$$

Consider a two-factor HJM model where the initial forward curve is given as 6% for one year and 7% between one and two years.The evolution of continuously-compounded one-year forward rates beginning at time $$T$$ ,is given by the following binomial process with two shock terms: $f ( t + 1 , T ) = f ( t , T ) + \alpha \pm 0.01 \pm 0.01$ ,where the forward rate movements are equiprobable.What this means is that the forward rate may move up by either 0.02 with probability 1/4,or move down by 0.02 with probability 1/4,or remain the same with probability 1/2.What is the risk-neutral drift ( $\alpha$ ) for $f ( 1,1 )$ ?

A) $- 0.0002$
B) $$- 0.0001$$
C) $$+ 0.0001$$
D) $+ 0.0002$
