Solution

The correct option is A kill the micro-organisms and other harmful bacteria
Pasteurization is the process of heating milk up and then quickly cooling it down to eliminate certain bacteria. Generally, chilled milk is heated from 4 °C to a pasteurization temperature of 72 °C, held at that temperature for 15 seconds, and then chilled to 4 °C again.
