Answer 1

`{ \underline{ \sf{O _(2) \: is \: reduced}}}`

Step-by-step explanation:

Reduction means when a reactant loses oxygen or gains hydrogen.

In the equation:

Hydrogen molecule, it neither gains nor loses hydrogen, but it gains oxygen. so :

`{ \sf{H _(2) \: is \: excluded}}`

Oxygen molecule loses one oxygen atom, and gains four hydrogen atoms, hence it is reduced.
