The correct option is B Placing the gametes in the fallopian tube
In GIFT, the sperm and eggs are just mixed together before being inserted and one of the eggs will become fertilized inside the fallopian tubes. This procedure involves stimulating the ovaries to produce more than one egg per cycle, like in IVF. These eggs are harvested and then placed in the fallopian tube of the mother along with the sperm collected from the father. Normal fertilization takes place, and the natural order of events in pregnancy follow.
