Solution

The correct option is B I > III > II
The correct reacting order of hydrogen is I > III > II, because atomic hydrogen has only one unpaired electron, which will be reacted with the other electron of other atom. In chemistry, nascent hydrogen is non-ionised, monoatomic hydrogen that exists transiently after the reduction of hydrogen ions. Lastly, dihydrogen is stable and it won't participate in reactions.
