D is the correct answer. 1,2-dimethylbenzene is the ortho isomer, 1,3-dimethylbenzene is the meta isomer, and 1,4-dimethylbenzene is the para isomer.

D
There are different configurations for dimethylbenzene depending on where the two methyl groups attach to the benzene ring. O (ortha), P (para) and M (meta) and each one has its' own energy level. If the sides groups get too big, then some shapes are forbidden. It's been a while since Orgo, can't remember all this stuff off the top of my head. I guess I wasn't asleep in class that day...
Good luck!

I suspect that the original poster has missed out a few important words - like "has no dipole moment".
p-dimethylbenzene has no dipole moment.
