Options

A. `3-4`
B. `10-15`
C. `25-30`
D. `250-300`

Answer

To determine the number of proglottids present in Echinococcus granulosus, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Echinococcus granulosus is a small tapeworm, commonly referred to as the dog tapeworm. It is important to recognize its characteristics and classification.

**Hint**: Remember that Echinococcus granulosus is often associated with dogs and is known for its small size.

2. **Understand Proglottids**: Proglottids are segments of a tapeworm's body. Each proglottid can contain reproductive organs, and they can be classified into immature, mature, and gravid (fertilized) proglottids.

**Hint**: Proglottids are crucial for the reproduction of tapeworms, and their classification helps in understanding the life cycle of the organism.

3. **Determine the Number of Proglottids**: In Echinococcus granulosus, the total number of proglottids is typically around 3 to 4. This includes:
- 1 immature proglottid
- 2 to 3 mature proglottids
- 1 gravid proglottid

**Hint**: Focus on the total count of proglottids when considering their different types.

4. **Conclusion**: Therefore, the number of proglottids present in Echinococcus granulosus is 3 to 4.

**Hint**: Always summarize your findings clearly to reinforce your understanding.

### Final Answer:
The number of proglottids present in Echinococcus granulosus is 3 to 4.
