QUESTION

Following tests used for detection of certain quality parameters in liquid milk samples:

List I (Tests)List II (Parameters)
(a) Alcohol-alizarin test(i) Fat content
(b) Gerber test(ii) Acidity
(c) Rosalic acid test(iii) Cleanliness
(d) Sediment test(iv) Neutralisers

Match as (a), (b), (c), (d):

OPTIONS

(A) (ii), (iii), (i), (iv)
(B) (ii), (i), (iv), (iii)
(C) (iv), (i), (ii), (iii)
(D) (iii), (ii), (i), (iv)

ANSWER

(B) (ii), (i), (iv), (iii)

EXPLANATION

Alcohol-alizarin assesses developed acidity and heat stability; the Gerber test measures fat; the rosalic acid test detects added neutralizers; and the sediment test assesses visible dirt or cleanliness. This gives the sequence (ii), (i), (iv), (iii), corresponding to option (B).
