Ozone is spread in the swimming pool because it:

Options

A. Absorbs UV radiations
B. Acts as disinfectant
C. Easily available from `O_(2)`
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Ozone**: Ozone (O₃) is a molecule composed of three oxygen atoms. It is known for its strong oxidizing properties.

2. **Role of Ozone in Swimming Pools**: Ozone is used in swimming pools primarily for its disinfectant properties. It helps in keeping the water clean and safe for swimmers.

3. **Reasons for Using Ozone**:
- **Effective Disinfectant**: Ozone is an effective disinfectant that helps in killing bacteria and viruses present in the water. It does this through a process called oxidation, where ozone reacts with these microorganisms, leading to their destruction.
- **Improves Smell and Visibility**: Ozone improves the overall smell and visibility of the pool water, making it more pleasant for users.
- **Oxidizes Metals**: Ozone can oxidize metals like manganese, iron, and sulfur into soluble particles, which can then be easily filtered out of the water. This helps in preventing staining and maintaining water clarity.
- **Bleaching Effect**: Ozone has a bleaching effect on discolored water, helping to restore its clarity and appearance.

4. **Conclusion**: Given these properties, the main reason ozone is spread in swimming pools is that it acts as an effective disinfectant, addressing various water quality issues.

5. **Evaluating Options**:
- The option stating that ozone absorbs UV rays is incorrect in this context.
- The option regarding ozone being easily available from O₂ is also incorrect.
- The option stating "all of the above" is incorrect as well.

6. **Final Answer**: Therefore, the correct answer is that ozone is spread in swimming pools because it acts as an effective disinfectant.
