Choose the correct option w.r.t group assigned.

Options

B. Methanogens `+` Halophiles `to` Archaebacteria
C. Puffballs `+` Morels `to` Basidiomycetes
D. more than one option is correct

Answer

To solve the question regarding the correct options with respect to the assigned groups, we will analyze each group and determine their classifications step by step.

### Step-by-Step Solution:

1. **Diatoms and Golden Algae**:
- Diatoms are known to be the chief producers (autotrophs) in oceans.
- Both diatoms and golden algae belong to the group called **Chrysophytes**.
- Diatoms have a unique glass-like cell wall made of hydrated silica.
- **Conclusion**: This option is correct.

2. **Methanogens and Halophiles**:
- Methanogens are organisms that produce methane as a by-product of their metabolism.
- Halophiles are organisms that thrive in high-salinity environments.
- Both of these groups belong to the domain **Archaebacteria**.
- They are known as extremophiles, as they can survive in extreme conditions like high salinity and high temperatures.
- **Conclusion**: This option is also correct.

3. **Puffballs and Morals**:
- Puffballs belong to the class **Basidiomycetes**.
- They produce club-like stalks called **Basidia**.
- Morals, on the other hand, belong to the class **Ascomycetes** (sac fungi).
- Therefore, the statement that both Puffballs and Morals belong to Basidiomycetes is incorrect.
- **Conclusion**: This option is incorrect.

4. **More than one option is correct**:
- Since options 1 and 2 are correct while option 3 is incorrect, it follows that there is more than one correct option.
- **Conclusion**: This statement is true.

### Final Answer:
The correct answer is: **More than one option is correct**.
