Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
From electrochemical series it can be seen that,
as reduction potential ( $E^{0} C l_{2} / C l^{θ}$ )> $E^{0} B r_{2} / B r^{θ}$ or $E^{0} a v e I_{2} / I^{θ}$ so it higher tendency to reduce and it can oxidise bromide and iodide ions so
$C l_{2} + B r^{θ} \to 2 C l^{θ} + B r_{2}$
$C l_{2} + I^{θ} \to 2 C l^{θ} + I_{2}$
