5 samples of pasteurized milk from a single lot were analyzed and their total plate counts were (cfu/ml): 25,000; 37,000; 15,000; 45,000 and 20,000.
Which of the following statements are true with respect to n, c and quality of the lot on the basis of the given data:

• A. n=5; c= 2; acceptable
• B. n=5; c=3; satisfactory
• C. n=5; c= 2; satisfactory
• D. n=5; c= 3; unsatisfactory

Hint:

In FSSAI "n, c, m, M" plans:
- All samples below 'm' = Satisfactory.
- Up to 'c' samples between 'm' and 'M' = Satisfactory.
- Any sample above 'M' or more than 'c' samples above 'm' = Unsatisfactory.
