Options

A. GIFT
B. ZIFT
C. ICSI
D. ET

Explanation

**Step-by-Step Solution:**

1. **Understanding the Context**: The question pertains to assisted reproductive technology (ART), which includes various techniques designed to help couples facing infertility issues.

2. **Identifying ART Techniques**: There are several ART techniques, including in vitro fertilization (IVF), zygote intra-fallopian transfer (ZIFT), gamete intra-fallopian transfer (GIFT), and intracytoplasmic sperm injection (ICSI).

3. **Explaining In Vitro Fertilization (IVF)**: IVF is the process where ova (eggs) from the female and sperm from the male are combined in a laboratory setting to facilitate fertilization.

4. **Understanding ICSI**: Among the various techniques, ICSI is specifically designed for cases where sperm needs to be directly injected into the ovum. In this method, a single sperm is injected directly into the cytoplasm of an egg.

5. **Conclusion**: The method of directly injecting a sperm into an ovum in assisted reproductive technology is called **Intracytoplasmic Sperm Injection (ICSI)**.
