उत्तर
(A)-(i), B-(iii), (C)-(iv), (D)-(ii)
Explanation:
- Gamete intrafallopian transfer (GIFT): In this procedure, a woman's ovaries are removed, and the man's sperm and eggs are put in one of the fallopian tubes.
- Intracytoplasmic sperm injection (ICSI): In this method, the zygote is created in vitro, or in a lab, when the sperm is directly placed into an ovum. Now ZIFT is transferring this zygote into the female's body.
- Zygote intrafallopian transfer (ZIFT): Following fertilisation, the embryo is transferred using this method directly into the female's fallopian tube.
- Intrauterine insemination (IUI): In this technique, the sperm are transferred into a female uterus using a long, narrow tube.
