Second largest phylum of invertebrates is____________?
Correct answer: C. Mollusca
- A. Porifera
- B. Arthropoda

Explanation
Arthropoda is the largest animal phylum, and Mollusca is generally considered the second largest in number of described species. Chordata is much smaller, while Porifera is not the second-largest animal phylum. The likely trap is b, which identifies the largest rather than the second-largest phylum.
