The technique called gamete intrafallopian transfer (GIFT) is recommended for those females who cannot produce an ovum, who cannot retain the foetus inside the uterus, whose cervical canal is too narrow to allow passage for the sperms, or who cannot provide a suitable environment for fertilization.

GIFT is an assisted reproductive technology. It is known as gamete intrafallopian transfer. The eggs are retrieved from the ovaries of the female. The male provides a sperm sample the same day that the eggs are retrieved. The eggs are then mixed with the sperm in a catheter and implanted in the uterus. So, the correct answer is option A.
