D. In vitro `rarr a, c, e" "`In vivo `rarr` b, d

Answer

To determine the correct type of fertilization for the assisted reproductive techniques (ART) listed (ZIFT, IUT, ICSI, GIFT, AI), we need to classify them as either in vivo (fertilization occurring inside the body) or in vitro (fertilization occurring outside the body). Here’s a step-by-step breakdown:

### Step 1: Understand the Definitions
- **In Vivo Fertilization**: Fertilization that occurs inside the body.
- **In Vitro Fertilization**: Fertilization that occurs outside the body, typically in a laboratory setting.

### Step 2: Analyze Each Technique
1. **ZIFT (Zygote Intrafallopian Transfer)**:
- The zygote is formed outside the body and then transferred to the fallopian tube.
- **Classification**: In Vitro (fertilization occurs outside the body).

2. **IUT (Intrauterine Transfer)**:
- A blastocyst (developed embryo) is transferred into the uterus after fertilization occurs outside the body.
- **Classification**: In Vitro (fertilization occurs outside the body).

3. **ICSI (Intracytoplasmic Sperm Injection)**:
- A single sperm is injected directly into an egg, which is done outside the body.
- **Classification**: In Vitro (fertilization occurs outside the body).

4. **GIFT (Gamete Intrafallopian Transfer)**:
- Both male and female gametes are placed in the fallopian tube where fertilization occurs inside the body.
- **Classification**: In Vivo (fertilization occurs inside the body).

5. **AI (Artificial Insemination)**:
- Sperm is introduced into the female reproductive tract (usually the vagina) to facilitate fertilization inside the body.
- **Classification**: In Vivo (fertilization occurs inside the body).

### Step 3: Summarize the Classifications
- **In Vitro Techniques**: ZIFT, IUT, ICSI
- **In Vivo Techniques**: GIFT, AI

### Conclusion
The correct types of fertilization for the techniques listed are:
- **In Vitro**: ZIFT, IUT, ICSI
- **In Vivo**: GIFT, AI

Thus, the answer to the question is that ZIFT, IUT, and ICSI are examples of in vitro fertilization, while GIFT and AI are examples of in vivo fertilization.
