Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
(I) Down the group, size of the halogen increases thereby increasing the strength of Vanderwaal forces. And hence boiling point of $B r_{2}$ is higher than $C l_{2}$ .
(II) Bromine has stronger dispersion forces due to the above-explained strength of Van der Waal forces.
