Correct Option: B

In vitro fertilization is a process by which an egg is fertilized by sperm outside the body. The process involves monitoring a woman's ovulatory process, removing ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a fluid medium in a laboratory. The fertilized egg (zygote) is then transferred to the patient's uterus with the intention of establishing a successful pregnancy.
