Correct option is A
The process of breaking fat globules into uniform sizes in milk is called homogenization. Homogenization is a mechanical process that reduces the size of fat globules in milk, creating a more uniform distribution. This prevents cream separation and improves the texture and stability of dairy products. During homogenization, milk is forced through a fine nozzle under high pressure, breaking down the fat globules into smaller particles that remain dispersed throughout the milk.
