Answer:
B. For application on skin
Explanation:
Cream such as ointment ( a smooth oily preparation that is rubbed on the skin for medicinal purposes or as a cosmetic) is a colloid as it's made up of tiny particles of fat dispersed in water. The particles making up a colloid are smaller than those in a suspension. If you put cream in a jar and shake for a about 10 minutes the fat molecules stick together, making butter and a liquid called buttermilk.
