Read the following text and answer the following questions on the basis of the same:
During sexual reproduction, the male inserts the sperm into the female reproductive tract, and sperm receive by the ovary and after that sperm fuse with the egg (ovum) in the ampullary region, this process is called fertilization, haploid nucleus of sperm fuse with that of ovum to form Diploid zygote.
Fertilization take place in

Options

A. Vagina
B. Follicle
C. Uterus
D. Fallopian tube

Explanation

**Step-by-Step Solution:**

1. **Understanding the Process of Fertilization:**
- During sexual reproduction, the male deposits sperm into the female reproductive tract. This is the initial step where sperm is introduced.

2. **Sperm Reception:**
- The sperm travels through the female reproductive tract and is received by the ovary. However, it is important to note that the sperm does not actually enter the ovary; instead, it reaches the egg (ovum) that is released from the ovary.

3. **Fusion of Sperm and Egg:**
- The sperm then travels to the ampullary region of the fallopian tube, where it meets and fuses with the egg. This fusion is known as fertilization.

4. **Formation of the Zygote:**
- The haploid nucleus of the sperm fuses with the haploid nucleus of the egg, resulting in the formation of a diploid zygote. This zygote contains the full set of chromosomes.

5. **Location of Fertilization:**
- The fertilization process occurs specifically in the ampullary region of the fallopian tube, which is the correct answer to the question.

**Final Answer:**
Fertilization takes place in the ampullary region of the fallopian tube.
