Select the correct answer about Litmus.

Options

A. Red litmus converted into blue due to acids
B. Red litmus converted into green due to presence of bases
C. Red litmus converted into blue due to presence of bases
D. None of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Litmus**: Litmus is a natural pH indicator derived from lichens. It is commonly used to test the acidity or basicity of a solution.

2. **Identifying Litmus Colors**: Litmus paper comes in two colors: red and blue. Red litmus paper is used to test for bases, while blue litmus paper is used to test for acids.

3. **Reaction with Bases**: When red litmus paper is placed in a basic solution, it changes color from red to blue. This indicates the presence of a base.

4. **Reaction with Acids**: Conversely, when blue litmus paper is placed in an acidic solution, it changes color from blue to red. This indicates the presence of an acid.

5. **Evaluating the Statements**:
- **Option A**: "Red litmus converted into blue due to acids" - This is incorrect because acids turn blue litmus red, not red litmus blue.
- **Option B**: "Red litmus converted into green due to presence of bases" - This is incorrect as red litmus does not turn green; it turns blue in the presence of bases.
- **Option C**: "Red litmus converted into blue due to presence of bases" - This is correct because red litmus does indeed turn blue in the presence of a base.
- **Option D**: "None of this" - This is incorrect since we have identified a correct statement.

6. **Conclusion**: The correct answer is **Option C**: "Red litmus converted into blue due to presence of bases."
