The fertilisation in mammals including human beings takes place in

Options

A. Vestibule
B. Vagina
C. Fallopian tubes
D. Uterus

Answer

**Step-by-Step Solution:**

1. **Understanding Fertilization**: Fertilization is the biological process where the male gamete (sperm) fuses with the female gamete (ovum) to form a zygote. This is the first step in the development of a new individual.

2. **Identifying the Site of Fertilization in Mammals**: In mammals, including humans, fertilization typically occurs in a specific location within the female reproductive system.

3. **Evaluating the Options**:
- **Option 1: Vestibule**: The vestibule is part of the external genitalia and does not play a role in fertilization.
- **Option 2: Vagina**: The vagina is where semen is deposited during intercourse, but fertilization does not occur here.
- **Option 3: Fallopian Tubes**: The fallopian tubes (also known as uterine tubes or oviducts) are the correct location where fertilization occurs. Specifically, it usually happens in the ampulla region of the fallopian tube.
- **Option 4: Uterus**: The uterus is where implantation of the fertilized egg (zygote) occurs, but it is not the site of fertilization.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is **Option 3: Fallopian Tubes**.
