Show Answer
Answer:
Correct Answer: B
Solution:
Option B, $ 60{}^\circ -63{}^\circ C $ for 30 minutes, is the correct answer.
This is known as Low-Temperature Long Time (LTLT) pasteurization, or traditional method, in which milk is heated to $ 62.8{}^\circ C$ (145 degrees F) for at least 30 minutes.
This method helps kill bacteria in the milk, making it safe for consumption and extending its shelf life.
