Options

A. Asexual reproduction
B. Sexual reproduction
C. Fertilisation
D. None of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Gametes**: Begin by defining what gametes are. Gametes are the reproductive cells involved in sexual reproduction. In humans and many other organisms, there are two types of gametes: male gametes (sperm) and female gametes (ova or eggs).

2. **Fusion of Gametes**: The process of reproduction that involves the fusion of male and female gametes is crucial. When these two gametes combine, they form a zygote. This process is known as fertilization.

3. **Definition of Sexual Reproduction**: Sexual reproduction is defined as the type of reproduction that involves the combination of genetic material from two parents. This is characterized by the fusion of male and female gametes.

4. **Conclusion**: Therefore, the reproduction that starts from the fusion of male and female gametes is called **sexual reproduction**.
