An animal having triploblastic acoelomic condition is

Options

A. Ascaris
B. Periplaneta
C. Planaria
D. Sycon.

Answer

To determine which animal has a triploblastic acoelomic condition, we can follow these steps:

### Step 1: Understand the Terms
- **Triploblastic**: This refers to animals that have three germ layers: ectoderm, mesoderm, and endoderm.
- **Acoelomic**: This refers to animals that do not have a body cavity (coelom) between the digestive tract and the outer body wall.

### Step 2: Analyze the Options
- **Ascaris**: This is a nematode (roundworm) and is triploblastic but has a pseudocoelom (not acoelomic).
- **Periplaneta**: This is a cockroach (insect) from the phylum Arthropoda. It is also triploblastic but has a true coelom.
- **Planaria**: This is a flatworm from the phylum Platyhelminthes. It is triploblastic and is known to be acoelomic.
- **Cyclone**: This is likely a typo or misinterpretation, but if referring to a member of the phylum Cnidaria (like a jellyfish), they are typically diploblastic.

### Step 3: Identify the Correct Answer
From the analysis:
- The only option that is both triploblastic and acoelomic is **Planaria** (option C).

### Conclusion
Thus, the animal having a triploblastic acoelomic condition is **Planaria (option C)**.
