Correct answer: D. 142 &#160; &#176; C

C is a para isomer. The melting point of para-isomer is comparatively higher than the corresponding ortho and meta-isomers , because of more symmetrical nature; it fits into crystal lattice more readily and so, close packing of molecules in crystal lattice increases the intermolecular force of attraction between molecules. Hence C has highest melting point that is 142 &#160; &#176; C
