Solution

The correct option is D Ketone
$O H$
$2^{o} - A l c o h o l \Rightarrow R - | C H - R$
When $2^{o}$ alcohol is treated with $C r O_{3} / H_{2} S O_{4}$ , it produce ketone because it has only one hydrogen i.e. to be oxidized.
$R - C H | - R C r O_{3} / H_{2} S O_{4} - ------- \to R - C | | - R$
$O H$ $O$
ketone
