CoF₆^3- Absorbs Light in the Red Region of the Spectrum

CoF₆^3- absorbs light in the red region of the spectrum, while Co(NH₃) ₆³⁺ absorbs light on the blue region of the spectrum. This difference means that __________

A) the splitting of the d orbitals of the two complexes is nearly identical.
B) the value of the crystal field splitting is very small for both complexes.
C) the crystal field splitting is larger for the ammonia complex than for the fluoride complex.
D) the d_z² and d_x² - _y² orbitals are higher in energy than the d_xy, d_xz, and d_yz orbitals in CoF₆^3- and just the opposite splitting order for Co(NH₃) ₆³⁺.
E) the d_z² and d_x² - _y² orbitals are lower in energy than the d_xy, d_xz, and d_yz orbitals in CoF₆^3- and just the opposite splitting order for Co(NH₃) ₆³⁺.
