Solution

The correct option is B ${C u}^{+} a n d {C u}^{+}$
Oxidizing agents are substances which oxidises other substances and themselves get reduced.
Reducing agents are substances which reduces other substances and themselves gets oxidized.
In the given reaction $C u^{+}$ acts as both oxidizing agent by oxidizing to $C u I_{2}$ and reducing agent by reducing to $C u$ i.e. undergoing both oxidation and reduction itself.
So,option D is correct.
