Which of the following is universally found in all protozoans ?

Options

A. Pseudopodia
B. Presence of pellicle
C. Eukaryotic organisation
D. Contractile vacuole

Answer

To solve the question "Which of the following is universally found in all protozoans?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a characteristic that is universally found in all protozoans. Protozoans are a diverse group of unicellular organisms.

2. **Analyze the Options**:
- **Option A: Pseudopodia** - Not all protozoans have pseudopodia. They are primarily found in amoeboid protozoans.
- **Option B: Presence of Pellicle** - While some protozoans have a pellicle, it is not a universal feature across all protozoans.
- **Option C: Eukaryotic Organization** - All protozoans are classified as eukaryotes, meaning they have complex cells with a nucleus.
- **Option D: Contractile Vacuole** - Contractile vacuoles are found in some protozoans, but not all.

3. **Identify the Universal Characteristic**: From the analysis, the only characteristic that is universally found in all protozoans is their eukaryotic organization.

4. **Select the Correct Answer**: Therefore, the correct answer is **Option C: Eukaryotic organization**.

### Final Answer:
The characteristic that is universally found in all protozoans is **C: Eukaryotic organization**.
