Given below are two statements:
Statement $I$: Due to increase in van der Waals forces,the order of boiling points is $CH_3CH_2CH_2I > CH_3CH_2I > CH_3I$.
Statement $II$: As $para$-dichlorobenzene is more symmetric,its melting point is higher than $ortho$-dichlorobenzene,however its boiling point is lower than $ortho$-dichlorobenzene.
In the light of the above statements,choose the correct answer from the options given below:
