In mammals milk is digested by action of :
A Rennin
B Amylase
C Intestinal bacteria
D Invertase

Detailed Solution

Rennin, a proteolytic enzyme found in the gastric juice of infants (and calves), acts on the milk protein casein.
It converts soluble caseinogen into insoluble paracasein, which combines with calcium to form a curd. This keeps the milk longer in the stomach so that pepsin can digest it.
So milk is digested by the action of rennin.
