    Given below are two statements : Statement-I : Due to increase in van der Waals forces, the order of boiling points is CH3CH2CH2I>CH3CH2I>CH3I{CH}_{3}{CH}_{2}{CH}_{2}I > {CH}_{3}{CH}_{2}I > {CH}_{3}I. Statement-II : As p-dichlorobenzene (1,4-dichlorobenzene) is more symmetric, its melting point is higher than that of o-dichlorobenzene (1,2-dichlorobenzene); however, its boiling point is lower than that of o-dichlorobenzene. In the light of the above statements, choose the correct answer from the options given below :
