Maximum amount of protein is found in

Answer: Option C

Maximum amount of protein is found in Sheep milk.
The difference in the protein content is due to genetic variation among these animal species. Whey protein content was highest in sheep milk (0.74%) while the lowest content was found in cow milk (0.53%). NCN content was higher in sheep milk (1.31%) and lower in camel (0.91%) and goat milk (0.90%).
The whey protein in sheep milk is very digestible. Sheep milk contains 3 times more of this type of protein than goat's or cow's milk which also contributes to better digestibility.
