The correct option is
A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Iodometric reaction are redox sections.
Iodine reacts directions fact and quantitatively
with many organic and in organic substances
And it has low pH independent redox potential
and there is a Reversible Iodine/Iodide
reaction taking place.
i.e
2I⇌I2+2e−
∴ Here Iodides can aid in reduction is
Iodine can act as oxidising agent
depending upon the redox system involved
and these the given Assertion and
Reasoning are correct and Reasoning is
correct explanation for Assertion.
