उत्तर
Compound (II)
Reasons: The molecular structure of compound (II) shows that both the substituents (i.e. \[\ce{CH3}\] and \[\ce{Cl}\] are at para position. The para-isomers have higher melting points as compared to their ortho and meta-isomers. It is due to symmetry of para-isomers that fits in crystal lattice better as compared to ortho-and meta-isomers.
