Answer

To solve the question regarding the male and female gametes in Fucus, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**:
- Fucus is a genus of brown algae, commonly found in marine environments.

2. **Understand Gamete Characteristics**:
- In many organisms, gametes can be classified based on their motility. Male gametes are often motile, while female gametes are typically non-motile.

3. **Determine Male Gamete Characteristics**:
- In Fucus, the male gamete is known to be motile. This means it has the ability to move, usually due to the presence of flagella.

4. **Determine Female Gamete Characteristics**:
- The female gamete (ova) in Fucus is non-motile. This means it does not have the ability to move on its own and is typically larger than the male gamete.

5. **Conclude the Answer**:
- Based on the characteristics of the gametes in Fucus, we can conclude that the male gamete is motile and the female gamete is non-motile. Therefore, the correct answer is option C: motile and non-motile respectively.

### Final Answer:
The male and female gametes in Fucus are motile and non-motile respectively (Option C).
