• D. It depends upon pH of medium as sperm is more active in alkaline medium/

Answer 1

Answer: (A)

Sperm is viable for only 24 hours.

Sperms are ejaculate with pre-ejaculates as a thick suspension and they are more active in alkaline medium. After ejaculation, sperm can live inside the female body for around 5 days. Once inside the female reproductive tract, the sperm cells swim through the cervix and into the uterus to reach the fallopian tubes and female egg.

So, the correct option is 'Sperm is viable for only 24 hours'.
