Solution

The correct option is B Hyaluronidase, CPE, Zona lysine
Acrosome of the sperm contains various enzymes, such as hyaluronidase, corona penetrating enzyme (CPE), zona lysine. Upon coming into contact with the zona pellucida, the acrosomal enzymes begin to dissolve and the actin filament comes into contact with the zona pellucida, which lead to the fusion of sperm and ovum. Hence, option B is correct.
