Which among these are assisted reproductive techniques?
(I) GIFT (II) MRI
(III) ICSI (IV)ZIFT

Options

A. (I) and (II)
B. (II) and (IV)
C. (I), (III) and (IV)
D. (II), (III) and (IV)

Explanation

To determine which among the given options are assisted reproductive techniques (ART), let's analyze each option step by step.

### Step 1: Understand Assisted Reproductive Techniques (ART)
Assisted Reproductive Techniques are medical procedures used primarily to address infertility. They involve the manipulation of eggs, sperm, or embryos to achieve pregnancy.

### Step 2: Analyze Each Option
1. **GIFT (Gamete Intra-Fallopian Transfer)**:
- This technique involves the collection of eggs from a donor and transferring them directly into the fallopian tubes of a female. It is used when the female can provide a suitable environment for fertilization but cannot produce eggs herself.
- **Conclusion**: GIFT is an ART.

2. **MRI (Magnetic Resonance Imaging)**:
- MRI is a diagnostic imaging technique used to visualize internal structures of the body. It does not involve any reproductive procedures or techniques aimed at assisting reproduction.
- **Conclusion**: MRI is NOT an ART.

3. **ICSI (Intracytoplasmic Sperm Injection)**:
- ICSI is a procedure where a single sperm is injected directly into an egg using a micro-needle. This technique is used when there are issues with sperm quality or quantity and is a common ART method.
- **Conclusion**: ICSI is an ART.

4. **ZIFT (Zygote Intra-Fallopian Transfer)**:
- ZIFT involves transferring a zygote (an early-stage embryo) into the fallopian tubes. This technique is used when fertilization has already occurred outside the body, and the embryo is then placed in the fallopian tube to develop.
- **Conclusion**: ZIFT is an ART.

### Step 3: Summarize the Findings
Based on the analysis:
- GIFT is an ART.
- MRI is NOT an ART.
- ICSI is an ART.
- ZIFT is an ART.

### Final Answer
The assisted reproductive techniques among the given options are:
- (I) GIFT
- (III) ICSI
- (IV) ZIFT

Thus, the correct answer is options (I), (III), and (IV).
