`[Co(Cr_(2)O_(4))_(3)]^(3-)` is a

Options

A. `C_(2)O_(4)^(2-)` is strong field ligand hence causes pairing of electrons
B. `C_(2)O_(4)^(2-)` is a bidentate ligand hence causes pairing of electrons
C. `Co^(3+)` is a strong central atom hence in all complexes of `Co^(3+)` electrons are paired
D. `C_(2)O_(4)^(2-)` is a strong field ligand hence causes splitting of d-orbitals .
