Answer 1

The correct option is C Sperm is viable for only up to 24 hours.

Fertilization is the fusion of sperm and egg. Fertilization and the subsequent establishment of pregnancy together are referred to as conception. After ejaculation into the female reproductive tract, sperm remain alive and retain their ability to fertilize an ovum for an estimated 48 to 72 hours. The ovum remains fertile for 12 to 24 hours after ovulation.
