(iii)UHT – Ultra high temperature treatment

Explanation:

This temperature is sufficient to destroy all pathogenic bacteria, while significantly reducing the number of organisms that can cause spoilage. Performing an alkaline phosphatase test with a negative result will confirm that the milk has been adequately pasteurized so that it is safe for human consumption.
