Which statement best describes the internal phase in an oil-in-water emulsion?

Explanation:
In emulsions, the internal (dispersed) phase is the one that is broken into droplets and spread throughout the other phase. In an oil-in-water emulsion, the oil forms small droplets that are dispersed in a continuous water phase. So the internal phase is oil, while the external phase is water. This is what makes oil the correct description for the internal phase. If it were reversed, you’d have a water-in-oil emulsion with water as the dispersed phase.
