The two polar molecules would have a larger attractive force than a polar and a non-polar molecule.
Two polar molecules will align themselves so that the + end of one is near the - end of the other.
In the case of one polar and one non-polar, the polar molecule would have to induce a partial pole on the non-polar molecule. The + on the polar molecule would induce a partial - charge on the non-polar molecule. The attractive force between the induced charges and then polar molecule will not be as great as with full polar charges.
The attractive force between substance A and B would be greatest in choice (i), where both substances are polar.

Well the definition of polar says that the central molecule has lone pairs, if you have two substances with lone pairs then they will probably be more attracted to join.

polar and nonpolar has a large force of attraction because they are two opposite things (- vs +) ATTRACT eachother ( - vs- )repel eacother
