Sensory organs like antennae, eyes (compound and simple), statocysts or balancing organs are present in members of phylum

Options

A. Mollusca
B. coelenterata
C. Arthropoda
D. Echinodermata

Answer

To solve the question regarding which phylum contains sensory organs like antennae, compound and simple eyes, and statocysts, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sensory Organs**: The question mentions specific sensory organs: antennae, compound eyes, simple eyes, and statocysts (balancing organs).

2. **Analyze the Options**: The options provided are:
- A) Mollusca
- B) Cylindrota
- C) Arthropoda
- D) Echinodermata

3. **Review Characteristics of Each Phylum**:
- **Mollusca**: Members of this phylum, such as squids and octopuses, have simple eyes and some may have statocysts, but they do not typically have antennae.
- **Cylindrota**: This is not a widely recognized phylum in biological classification and is likely a distractor.
- **Arthropoda**: This phylum includes insects, arachnids, and crustaceans. They are characterized by having both compound and simple eyes, antennae, and statocysts for balance.
- **Echinodermata**: Members of this phylum, like starfish, have simple eyes but lack antennae and statocysts.

4. **Determine the Correct Answer**: Based on the characteristics reviewed, the phylum that possesses all the mentioned sensory organs (antennae, compound and simple eyes, and statocysts) is **Arthropoda**.

5. **Conclusion**: The correct answer to the question is **C) Arthropoda**.
