Chemistry redox

answer is A
is this question asking for the equations to be able to take place? i am a little confused


yes it’s asking if the reaction can take place
only options 1) and 2) work, because a more reactive non metal is replacing a less reactive non metal

Yes I agree it is asking if the reaction is feasible or not
The reactivity of halogens is F> Cl >Br >I
Since Cl and Br are more reactive than I they will replace it and thus the answer is A
