In human, fertilization usually occurs at:

Options

A. Vagina
B. Cervix
C. Fallopian tube
D. Infundibulum

Answer

**Step-by-Step Solution:**

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

2. **Location of Fertilization**: In humans, fertilization typically occurs in the female reproductive system. Specifically, it takes place in the fallopian tubes, which are also known as oviducts.

3. **Role of the Fallopian Tubes**: The fallopian tubes serve as the pathway for the ovum to travel from the ovary to the uterus. When an ovum is released during ovulation, it is captured by the fimbriae of the fallopian tube, where it may encounter sperm.

4. **Conclusion**: Therefore, the correct answer to the question is that fertilization usually occurs in the fallopian tube.
