Answer 1

The correct option is C Oxygen

$\begin{array}{c}\text{Flourine is more Electronegative element than Oxygen and Oxygen is more Electronegative}\\ \text{than Chlorine.}\\ \text{Hence, Flourine can oxidise Oxygen whereas Chlorine reduced Oxygen.}\\ \text{Hence option}\left(C\right)\text{is correct.}\end{array}$
