B. Entire foregut is lined by cuticle
C. Male have spermatheca in 6th segment
D. Female have caudal style

Answer

To determine what is true about cockroaches, we need to analyze the given statements one by one.

### Step-by-Step Solution:

1. **Identify the Classification of Cockroach**:
- Cockroaches belong to the class Insecta and the phylum Arthropoda. This classification is important as it provides context for understanding their biological characteristics.

**Hint**: Remember the classification hierarchy: Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.

2. **Evaluate Each Statement**:
- **Option 1**: "Cockroach is a ureotalic organism."
- This statement is incorrect. Cockroaches excrete uric acid, which classifies them as uricotelic organisms, not ureotelic.

**Hint**: Ureotelic organisms excrete urea, while uricotelic organisms excrete uric acid.

- **Option 2**: "The entire foregut is lined by cuticle."
- This statement is correct. The foregut of a cockroach is indeed lined with a cuticle, which is a protective layer.

**Hint**: The foregut includes structures like the crop and gizzard, which are involved in food storage and grinding.

- **Option 3**: "Males have spheromethica in six segments."
- This statement is incorrect. Spheromethica is a structure found in females, specifically in the sixth abdominal segment.

**Hint**: Remember that male and female cockroaches have different reproductive structures.

- **Option 4**: "Females have cordal style."
- This statement is incorrect. The cordal style is present in males, not females. Females have a different structure for reproduction.

**Hint**: The presence of the cordal style can be used to differentiate male cockroaches from females.

3. **Conclusion**:
- After evaluating all options, the only true statement about cockroaches is **Option 2**: "The entire foregut is lined by cuticle."

### Final Answer:
The correct answer is **Option 2**: The entire foregut is lined by cuticle.
