What is correct

Options

A. Slime Moulds are haploid
B. Protozoans lack cell wall
C. Pellicle is absent in Euglena
D. Dinoflagellates are immobile.

Answer

To determine the correct statement from the options provided, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Analyze the First Option: "Slime molds are haploid."**
- Slime molds can exist in both haploid and diploid forms. They typically have a life cycle that includes both stages, but they are not exclusively haploid. Therefore, this statement is incorrect.

2. **Analyze the Second Option: "Protozoans lack cell wall."**
- Protozoans are unicellular eukaryotic organisms that belong to the kingdom Protista. They are similar to animal cells in that they do not have a cell wall. This statement is correct.

3. **Analyze the Third Option: "Pellicle is absent in Euglena."**
- Euglena possesses a pellicle, which is a flexible outer covering that provides shape and support. Therefore, this statement is incorrect.

4. **Analyze the Fourth Option: "Dinoflagellates are immobile."**
- Dinoflagellates are known for their motility, as they possess flagella that allow them to move. Thus, this statement is also incorrect.

### Conclusion:
The correct statement among the options provided is: **"Protozoans lack cell wall."**
