Solution

The correct option is C Secreting sperm lysin to dissolve covering membrane of oocyte
During copulation of frogs, the male remains inactive and female swims. The sperms dissolve the vitelline membrane and the plasma membrane of the ovum by proteolysis. The proteolytic enzyme involved is sperm lysin which is secreted by the acrosome of the sperm.
Thus, the correct answer is option D.
