Organisms having cells without nuclear envelope and cell organelles belong to
(i) Fungi
(ii) Protista
(iii) Cyanobacteria
(iv) Archaebacteria

Options

A. (i) and (ii) only
B. (iii) and (iv) only
C. (i) and (iv) only
D. (ii) and (iii) only

Explanation

To solve the question regarding which organisms have cells without a nuclear envelope and cell organelles, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics of Prokaryotes and Eukaryotes**:
- Prokaryotic cells do not have a nuclear envelope or membrane-bound organelles.
- Eukaryotic cells have a defined nucleus (with a nuclear envelope) and various membrane-bound organelles.

2. **Analyze the Given Options**:
- (i) **Fungi**: These are eukaryotic organisms that have a nuclear envelope and organelles.
- (ii) **Protista**: This group also consists of eukaryotic organisms, which have a nuclear envelope and organelles.
- (iii) **Cyanobacteria**: These are prokaryotic organisms (also known as blue-green algae) that lack a nuclear envelope and organelles.
- (iv) **Archaebacteria**: These are also prokaryotic organisms that lack a nuclear envelope and organelles.

3. **Determine the Correct Answer**:
- Since both Cyanobacteria and Archaebacteria are prokaryotic and do not have a nuclear envelope or organelles, the correct answer to the question is either (iii) Cyanobacteria or (iv) Archaebacteria.

4. **Final Conclusion**:
- The organisms having cells without a nuclear envelope and cell organelles belong to the groups of Cyanobacteria and Archaebacteria.

### Final Answer:
The correct options are (iii) Cyanobacteria and (iv) Archaebacteria.
