_____ contain water and may be diluted with aqueous or water-miscible solutions.

Explanation:
This describes oil-in-water emulsions. In O/W emulsions, water is the continuous phase surrounding oil droplets. Because the external phase is water, you can mix the emulsion with additional water or aqueous solutions to dilute it without breaking the emulsion (within stability limits). In contrast, water-in-oil emulsions have oil as the continuous phase, so adding water is not as straightforward and tends to destabilize them. Hydrophobic ointments, on the other hand, contain little to no water.
