In the anion `HCOO^-` , the carbon-oxygen bonds are found to be of equal length. This is due to :

Options

A. The anion is obtained by the removal of a proton from the acid molecule.
B. Electronic orbitals of carbon atoms are hybridised.
C. The `C=O` bond is weaker than `C-O` bond.
D. The anion `HCOO^(-)` has two equally stable resonating structures.
