Which One of the Following Formulas Correctly Defines the Relationship

Which one of the following formulas correctly defines the relationship to which it is associated?

A) Interest rate parity: (F₁) /(S₀) = (1 + R_FC) (1 + R_CDN)
B) Relative PPP: E(S_t) = [S₀][1 + (h_CDN - h_FC) ]^t
C) International Fisher effect: R_CDN - h_CDN = h_FC - R_FC
D) Uncovered interest rate parity: E(S_t) = [S₀][1 + (R_FC - R_CDN) ]^t
E) Unbiased forward rate: F₃ = (S₀)
