Text Solution
Verified by ExpertsThe correct answer is:
A
Despite the above values of the standard reduction potentials, 
is able to oxidize iodide to 
due to all the species like 
, and 
being present together in the solution. The cumulative effect of this results in the 
reduction potential being 
that makes the reaction feasible.
Therefore, CuI or 
exists instead of 
as 
oxidises 
to 
and so and (R) are true with (R) explaining .
