Solution

The correct option is C $F_{2}$ and $I^{-}$
Because of high standard reduction potential of $F_{2}$ , it readily reduces to $F^{-}$ . So it oxidises other elements strongly. So, it is the strongest oxidising agent.
$I_{2}$ has the lowest standard reduction potential here. $I^{-}$ oxidises itself strongly and reduces others. So, it is a strong reducing agent.
Hence, option (a) is correct.
