Moneran group that includes only autotrophic members is

Options

A. Bacteria
B. Mycoplasma
C. Cyanobacteria
D. Actinomycetes

Answer

To solve the question "Moneran group that includes only autotrophic members is," we will analyze the options provided and determine which one fits the criteria of being exclusively autotrophic.

### Step-by-Step Solution:

1. **Understand the Kingdom Monera**: The kingdom Monera consists of prokaryotic organisms, primarily bacteria. This group includes both autotrophic (organisms that can produce their own food) and heterotrophic (organisms that depend on other organisms for food) members.

2. **Analyze the Options**:
- **Option A: Bacteria**: This is a broad category that includes both autotrophic and heterotrophic organisms. Therefore, it cannot be the correct answer.
- **Option B: Mycoplasma**: Mycoplasmas are a type of bacteria that are known to be heterotrophic. Thus, this option is also incorrect.
- **Option C: Cyanobacteria**: Cyanobacteria are known as blue-green algae and are autotrophic. They can perform photosynthesis, producing their own food using sunlight and have chlorophyll pigments.
- **Option D: Actinomycetes**: These are a group of bacteria that are primarily heterotrophic. Hence, this option is not correct.

3. **Identify the Correct Answer**: Based on the analysis, the only group among the options that includes only autotrophic members is **Cyanobacteria**.

### Final Answer:
The moneran group that includes only autotrophic members is **Cyanobacteria**.
