Answer:
The correct answer is between 12 to 24 hours.
Explanation:
After an unfertilized egg has left the ovary, its lifespan lies in between 12 to 24 hours, according to the American Pregnancy Association. A solitary developed egg is discharged by the ovary and is pushed towards the fallopian tube, where it possesses the tendency to get fertilized by the sperm every month. The fusion of the egg and the sperm to produce the diploid zygote is known as fertilization.
