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.
