Answer 1

Answer: (B)

In-vitro fertilization is a technique of letting fertilisation of the male and female gametes (sperm and egg) occur outside the female body, e.g., intracytoplasmic sperm injection (ICSI), zygote intra-fallopian transfer (ZIFT), IUT. In-vivo fertilization of a ripe egg occurs within the uterus of a fertile donor female, rather than in an artificial medium, for subsequent nonsurgical transfer to an infertile recipient, e.g., gamete intra-fallopian tube transfer (GIFT), artificial insemination (AI).
