Options

A. Multiflagellated
B. Pentaflagellated
C. Biflagellated
D. Non-flagellated

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks about the nature of fern sperms, specifically referring to them as antherozoids.

2. **Defining Antherozoids:** Antherozoids are the male gametes produced in the male reproductive organ called the antheridium of ferns.

3. **Types of Flagellation:** The options given describe the types of flagellation:
- Multi-flagellated: More than two flagella.
- Pentaflagellated: Exactly five flagella.
- Biflagellated: Exactly two flagella.
- Non-flagellated: No flagella present.

4. **Analyzing Fern Antherozoids:** In ferns, the antherozoids are known to have multiple flagella. This adaptation is crucial for their movement in water during fertilization.

5. **Conclusion:** Based on the characteristics of fern antherozoids, the correct answer is that they are multi-flagellated.

6. **Final Answer:** The correct option is **multi-flagellated**.
