Observe the following reactions:
$I$. $2H_2O_{(l)} + 2Na_{(s)} \rightarrow 2NaOH_{(aq)} + H_{2(g)}$
$II$. $2H_2O_{(l)} + 2F_{2(g)} \rightarrow 4H^{+}_{(aq)} + 4F^{-}_{(aq)} + O_{2(g)}$
Identify the correct statement from the following:

• A
  In both reaction $I$ and reaction $II$,water is oxidized.
• B
  In both reaction $I$ and reaction $II$,water is reduced.
• C
  In reaction $I$ water is reduced and in reaction $II$ water is oxidized.
• D
  In reaction $I$ water is oxidized and in reaction $II$ water is reduced.
