Hint: GIFT- Gamete Intra Fallopian Transfer method is usually used in females who cannot produce ova but can provide a suitable environment for fertilization and further development of the embryo in the oviducts. In this case, the ovum from the donor female is removed surgically and is then introduced into the fallopian tube of such females.

Complete answer: Option (A)- Transfer of zygote into a fallopian tube
This is incorrect because the zygote is not transferred. Instead, the gametes i.e., (both eggs and sperm) are injected into the fallopian tubes.

Option (B)- Transfer of embryo into the uterus.
This is not right, because the transfer of the gamete is done in the fallopian tube. The transfer is not done in the uterus.

Option (C) - Transfer of mixture of sperms and eggs.
Gamete Intra Fallopian Transfer (GIFT) uses multiple eggs that are collected from the ovaries. The eggs are then placed into a thin flexible tube (catheter) along with the sperm to be used. Both the eggs and sperm are collectively known as gametes are then injected through surgical procedure into the fallopian tubes called laparoscopy. The doctor will also use general anesthesia.

Option (D) is none of the above.
This option is not right because option (C) is correct.

So, the answer is option C, Transfer of mixture of sperms and eggs.

Note: Some infertile couples are affected by the conditions which prevent the sperm and egg from traveling through a fallopian tube. (This is where the process of fertilization and the first stage of cell division takes place.) GIFT is one of the Assisted Reproductive Technology (ART) procedures that are rarely used but it might improve the chances of conception in the fallopian tubes. The first step of this treatment is superovulation. Hormone injections are used to stimulate the ovaries to produce multiple eggs.
