Which of the following is correct match of character with phylum ?

Options

A. Platyhelminthes - psuedocoelom
B. Aschelminthes - Bisexual
C. Annelida - Radula
D. Mollusca - Mantle

Answer

To determine the correct match of character with phylum from the given options, we can analyze each option step by step:

1. **Option A: Platyhelminthes and Pseudocoelom**
- Platyhelminthes, also known as flatworms, are characterized by being acoelomate (having no body cavity). They do not possess a pseudocoelom. Therefore, this match is incorrect.

2. **Option B: Nematoda and Flexual**
- Nematoda, or roundworms, do possess a pseudocoelom, but the term "flexual" is not a standard term associated with this phylum. This option does not provide a clear or correct match, making it incorrect.

3. **Option C: Annelida and Radula**
- Annelida, or segmented worms, do not have a radula. The radula is a structure found in mollusks, used for feeding. Therefore, this match is also incorrect.

4. **Option D: Mollusca and Mantle**
- Mollusca is characterized by the presence of a mantle, which is a significant feature of this phylum. The mantle is a dorsal body wall that can cover the visceral mass and is involved in the secretion of the shell in many mollusks. Thus, this match is correct.

Based on the analysis, the correct answer is **Option D: Mollusca and Mantle**.
