Explanation / Answer

A)results from the tendency to maximize water contacts w/ nonpolar molecules

Reason: The hydrophobic effect is tendency of nonpolar molecules in a polar solvent (usually water) to interact with one another, and not to maximize water contacts w/ nonpolar molecules.

C)results from a change in pH of the solution

Reason: The role of pH is not involved in the hydrophobic reaction.

D)are the result of strong attractions b/w no polar regions

Reason: Hydrophobic effect are interactions between the nonpolar molecules, not only strong attractions b/w no polar regions.

E)are the result of strong attraction b/w water and no polar regions

Reason: Hydrophobic effect are interactions between the nonpolar molecules, not  the strong attraction b/w water and no polar regions

Hence A, C, D, and E are wrong.
