QUESTION
Specific gravity of milk is influenced by?
OPTIONS
(A) Fat
(B) Protein
(C) Lactose
(D) All of these
ANSWER
(D) All of these
EXPLANATION
Milk specific gravity reflects the combined effects of its constituents: fat tends to lower specific gravity because it is less dense than water, whereas proteins, lactose, and mineral solids tend to increase it. Since fat, protein, and lactose all influence the measurement, option (D) is correct.
