Name the technique by which baby conceived fertilisation that occurs outside the mother's body.

Options

A. Test tube baby
B. Fallopian tube baby
C. Both of these
D. None of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the name of a technique where fertilization occurs outside the mother’s body, leading to the conception of a baby.

2. **Identifying the Process**: In certain cases, when there are difficulties in natural fertilization, a medical procedure is used. This involves extracting an egg from the female and sperm from the male.

3. **In Vitro Fertilization (IVF)**: The extracted egg and sperm are combined in a controlled environment, typically a laboratory setting, which is referred to as "in vitro" (meaning "in glass"). This process allows for fertilization to occur outside the female's body.

4. **Formation of Zygote**: Once the sperm fertilizes the egg, a zygote is formed. This zygote can then develop into an embryo.

5. **Implantation**: After the zygote has developed sufficiently, it is implanted back into the female's uterus, where it can grow into a normal baby.

6. **Conclusion**: The technique described is known as In Vitro Fertilization (IVF), and it is commonly referred to as the "test tube baby" method.

**Final Answer**: The technique is called In Vitro Fertilization (IVF).
