Polarity is the ability to distinguish between the electric charge of a molecule or different chemical groups having dipoles or multipole moment. Polar molecules have polar bonds based on the difference in electronegativity between atoms bonded together. Polarity affects how solvents dissolve by following the idea that "like dissolves like" in other words, polar molecules are best dissolved in polar solvents and nonpolar molecules dissolve better in nonpolar solvents. Moreover, ionic solvents dissolve polar solutes. By this the final answer is E, similar polarity makes the solvent more likely to dissolve
