Which statement describes W/O emulsions?

Explanation:
Water-in-oil emulsions are emulsions where water exists as the dispersed droplets inside a continuous oil phase. In this type, tiny water droplets are spread throughout and surrounded by oil. That’s why the description that fits W/O is water droplets dispersed in oil. The other statements don’t describe this arrangement: being water-free would mean no water present at all, gas emulsions involve gas, and oil droplets dispersed in water describes an oil-in-water emulsion, the opposite arrangement.
