1, 2, 3 - butanetriol undergoes oxidative cleavage of `HIO_4` During this process

Options

A. 1 equivalent of `HlO_4` consumed & `HCO_2 H & H_3C-underset(O)underset(||)C-CO_2` H are formed
B. 2 equivalents of `HlO_4` consumed & `HCO_2 H,HCH = O & CH_3 - CH-O` are formed
C. 3 equivalents of `HIO_4` consumed & `HCO_2 H (2eq.)` & 1 eq. of `CH_3CO_2` H are formed
D. 2 equivalents of `HlO_4`consumed & 2 e.q . Of `HCO_2 H` & 1 eq. of `CH_3CH=O` is formed

Explanation

`underset(OH)underset(|)CH_2-underset(OH)underset(|)CH-underset(OH)underset(|)CH-CH_3 overset(HlO_4) rarr CH_3CHO + HCO_2 H + HCHO`
