When the zero curve is decreasing, which of the followings is true? a) The two-year zero rate, R(0,2), is equal to the one-year zero rate, R(0,1) b) The forward rate between year one and year two, i.e. F0(1,2), is lower than the one-year zero rate, R(0,1) c) The forward rate between year one and year two, i.e. F0(1,2), is between the one-year zero rate, R(0,1), and the two-year zero rate, R(0,2). That is R(0,1)
