which of the following processes is involved in the assisted reproductive technology known as 'GIFT'?

Options

A. Transfer of zygote into the fallopian tube
B. Transfer of zygote into the uterus
C. Transfer of ovum collected from donor to the follopian tube
D. Transfer of ovum collected from donor to the uterus

Answer

To solve the question regarding the process involved in the assisted reproductive technology known as GIFT (Gamete Intra-Fallopian Transfer), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding GIFT**: GIFT stands for Gamete Intra-Fallopian Transfer. It is a type of assisted reproductive technology (ART) where both eggs (ova) and sperm are transferred into a woman's fallopian tubes.

2. **Identifying the Options**: The options provided are:
- A. Transfer of zygote into the fallopian tube.
- B. Transfer of zygote into the uterus.
- C. Transfer of ovum collected from donor to the fallopian tube.
- D. Transfer of ovum collected from the donor to the uterus.

3. **Analyzing the Process**: In GIFT, the key process involves transferring the gametes (ova and sperm) directly into the fallopian tubes, where fertilization can occur naturally. This is different from other ART methods where zygotes or embryos are transferred.

4. **Selecting the Correct Option**:
- Option A refers to the transfer of a zygote, which is not the process in GIFT.
- Option B also refers to the transfer of a zygote, which is not correct.
- Option C correctly states the transfer of an ovum (egg) collected from a donor to the fallopian tube, which aligns with the GIFT procedure.
- Option D refers to the transfer of an ovum to the uterus, which is not part of GIFT.

5. **Conclusion**: The correct answer is **C. Transfer of ovum collected from donor to the fallopian tube**.
