Which one of the following statements is incorrect?

Options

A. Indica, tuberosum and leo represents the specific epithets
B. Physalis, Apes and Helianthus represents the generic epithets
C. Monocotyledonae and Dicotyledonae are the two classes of division Angiospermae
D. Phylum Chordata is largest phylum of kingdom Animalia.

Answer

To determine which statement is incorrect among the provided options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Specific Epithet**:
- The first statement mentions "indica tuberosum and leo represents the specific epithet."
- In binomial nomenclature, the specific epithet is indeed the species name.
- For example, in *Mangifera indica* (mango), "indica" is the specific epithet, and in *Solanum tuberosum* (potato), "tuberosum" is the specific epithet.
- The term "leo" refers to *Panthera leo* (lion), where "leo" is also the specific epithet.
- **Conclusion**: This statement is correct.

2. **Understanding Generic Epithet**:
- The second statement discusses "physalis epis and helianthus" as representing the generic epithet.
- The generic epithet refers to the genus name.
- For instance, *Physalis peruviana* (cape gooseberry) has "Physalis" as the genus, *Epis indica* (a type of plant) has "Epis" as the genus, and *Helianthus annuus* (sunflower) has "Helianthus" as the genus.
- **Conclusion**: This statement is also correct.

3. **Classes of Angiosperms**:
- The third statement claims "monocotilidine and dicotilidine are the two classes of division angiospermia."
- Angiosperms are indeed divided into two main classes: monocots (monocotyledons) and dicots (dicotyledons).
- **Conclusion**: This statement is correct.

4. **Largest Phylum of Kingdom Animalia**:
- The fourth statement states "phylancordata is the largest phylum of kingdom animalia."
- This statement is incorrect because the largest phylum in the kingdom Animalia is *Arthropoda* (which includes insects, arachnids, and crustaceans), not *Chordata* (which includes vertebrates).
- **Conclusion**: This statement is incorrect.

### Final Answer:
The incorrect statement is: "phylancordata is the largest phylum of kingdom animalia."
