Answer

To solve the question regarding the transfer of an ovum from a donor into the fallopian tube of a surrogate mother, we will analyze the options provided and identify the correct term for this procedure.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the transfer of an ovum from a donor into the fallopian tube of a surrogate mother. This involves assisted reproductive technology.

2. **Reviewing the Options**:
- **ET (Embryo Transfer)**: This typically involves transferring an embryo into the uterus, not the fallopian tube.
- **IUT (Intrauterine Transfer)**: This refers to transferring an embryo directly into the uterus.
- **GIFT (Gamete Intrafallopian Transfer)**: This involves placing the ovum (egg) and sperm directly into the fallopian tube, allowing fertilization to occur there.
- **ZIFT (Zygote Intrafallopian Transfer)**: This involves transferring a fertilized egg (zygote) into the fallopian tube.

3. **Identifying the Correct Procedure**: The procedure described in the question involves placing an ovum (egg) into the fallopian tube of a surrogate mother. The correct term for this is **GIFT (Gamete Intrafallopian Transfer)**, as it specifically refers to the transfer of gametes (in this case, the ovum) into the fallopian tube.

4. **Conclusion**: Based on the definitions and the context provided, the correct answer to the question is **GIFT (Gamete Intrafallopian Transfer)**.

### Final Answer:
The transfer of an ovum from a donor into the fallopian tube of a surrogate mother is called **GIFT (Gamete Intrafallopian Transfer)**.
