Arrange the following steps in order.

i. Sperm survive for a short period in the vagina's acidic secretions.
ii. The sperm travels through the uterus to the fallopian tube.

• B. iv - iii - ii - i
• C. i - iii - ii - iv
• D. iv - ii - iii - i

Answer 1

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.
