The test is done to identify incomplete pasteurization in milk?

Correct option is A

The test conducted to identify incomplete pasteurization in milk is the Alkaline Phosphatase Test. Alkaline Phosphatase is an enzyme present in raw milk, and its activity is destroyed during proper pasteurization. Therefore, if the test detects the presence of alkaline phosphatase in milk, it indicates incomplete pasteurization. The other options, MBE (Methylene Blue Dye Reduction Test), Alcohol test, and COB (Catalase Orange Bromocresol) test, are not specifically designed to identify incomplete pasteurization in milk.
