Solution

The correct option is B

Zygote into the fallopian tube


The correct option is B.

The explanation for the correct option:

  1. ART encompasses all fertility-related treatments.
  2. Amongst all, IVF (In vitro fertilization- literally fertilization in laboratory conditions is the most widely used procedure).
  3. It involves- surgical removal of eggs from a female's ovaries, fusing them with sperm in vitro (laboratory conditions). and ultimately returning the fertilized zygote or embryo to the female's body (mostly to fallopian tubes) or donating it to another female.
  4. It is widely useful in females with weakened or clogged fallopian tubes.

The explanation for the incorrect options:

Option A:

The transfer of a zygote(or embryo) into the uterus of a female is known as Embryo Transfer(ET), a type of ART.

Option C:

GIFT( Gamete intra-fallopian Transfer) is a technique that is helpful in conditions where a female cannot produce ova but can provide a suitable environment for fertilization for embryo development in the oviducts. It involves the transfer of the ovum into the fallopian tube.

Option D:

Embryos with up to 8 blastomeres can be transferred to fallopian tubes. Embryos with 8-16 blastomeres are mostly transferred to the uterus.

The final answer: Assisted reproductive technology (ART), IVF involves the transfer of Zygote into the fallopian tube.
