Taste receptors of Ascaris are

Options

A. Phasmids
B. Post-anal papilla
C. Dorsal lip
D. Ventrolateral lips

Answer

To answer the question regarding the taste receptors of Ascaris, we will analyze the options provided and identify the correct one.

### Step-by-Step Solution:

1. **Understanding Ascaris**:
- Ascaris is a genus of parasitic worms commonly known as roundworms. They primarily inhabit the intestines of their hosts and can cause various diseases.

2. **Identifying the Options**:
- The question provides four options regarding the taste receptors of Ascaris:
1. Phasmid
2. Post anal papilla
3. Dorsal lip
4. Ventral lateral lips

3. **Evaluating Each Option**:
- **Option 1: Phasmid**:
- Phasmids are sensory organs in nematodes, but they are not specifically responsible for taste. Therefore, this option is incorrect.
- **Option 2: Post anal papilla**:
- The post anal papilla is involved in sensory functions but is not specifically a taste receptor. Thus, this option is also incorrect.
- **Option 3: Dorsal lip**:
- The dorsal lip is known to be responsible for taste reception in Ascaris. This makes this option correct.
- **Option 4: Ventral lateral lips**:
- These lips are involved in chemoreception but are not specifically designated as taste receptors. Hence, this option is incorrect.

4. **Conclusion**:
- After evaluating all the options, the correct answer is **Option 3: Dorsal lip**, as it is responsible for taste receptors in Ascaris.

### Final Answer:
The taste receptors of Ascaris are located in the **Dorsal lip**.
