[Co(C(2)O(4))(3)]^(3-) is a...

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

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 .
