For entering the ovum the sperm penetrates the corona radiata and zona pellucida with the help of

A
Vaginal secretions
B
Sperm lysins secreted from acrosome
C
Uterine secretions
D
Fallopian tube secretions

Solution:

The secretions of the acrosome (sperm lysins) help the sperm enter into the cytoplasm of the ovum through the zona pellucida and the plasma. Some of the sperm lysins like hyaluronidase, corona penetrating enzyme (CPE) and zona lysin help in penetrating through corona radiata and zona pellucida of the ovum.
