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.
Site of fusion of sperm with an ovum.

Options

A. Infundibulum
B. Ampullary isthmic junction of oviduct
C. Cervix of uterus
D. Ovary

Explanation

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

1. **Understanding the Process of Fertilization:**
- In sexual reproduction, the male deposits sperm into the female reproductive tract.
- The sperm then travels through the female reproductive system to reach the egg (ovum).

2. **Location of Fertilization:**
- The sperm fuses with the ovum in a specific area known as the ampullary region of the oviduct (fallopian tube).
- This fusion of the sperm and ovum is referred to as fertilization.

3. **Formation of the Zygote:**
- During fertilization, the haploid nucleus of the sperm merges with the haploid nucleus of the ovum.
- This fusion results in the formation of a diploid zygote, which is the first cell of a new organism.

4. **Identifying the Site of Fusion:**
- Based on the information provided, the correct answer to the question regarding the site of fusion of sperm with an ovum is the ampullary region.

**Final Answer:**
- The site of fusion of sperm with an ovum is the **ampullary region**.
