Solution

The correct option is C

i - iii - ii - iv


The sperms first enter the vagina where they survive for a short time in the acidic secretion. They then reach the cervix from where the surviving sperms move to the uterus followed by fallopian tube. At last, they fuse or fertilize with the egg in the fallopian tube.
