Answer

To determine which element is not present in saccharin, we need to analyze the chemical structure of saccharin and identify the elements that are part of its composition.

### Step-by-Step Solution:

1. **Understanding Saccharin**: Saccharin is an artificial sweetener with the chemical formula C7H5NO3S. It contains a benzene ring and functional groups that include sulfonamide.

2. **Identifying Elements in Saccharin**: From the chemical formula, we can identify the following elements:
- **Carbon (C)**: Present in the benzene ring and other parts of the molecule.
- **Hydrogen (H)**: Present in the benzene ring and attached to the carbon atoms.
- **Nitrogen (N)**: Present in the amide group (–NH).
- **Oxygen (O)**: Present in the sulfonyl (–SO2) and carbonyl (–C=O) groups.
- **Sulfur (S)**: Present in the sulfonyl group.

3. **Listing the Given Elements**: The options provided are:
- 1. Sulphur
- 2. Phosphorus
- 3. Not present
- 4. Carbon
- 5. Potassium

4. **Analyzing Each Element**:
- **Sulfur**: Present in saccharin.
- **Phosphorus**: Not present in saccharin.
- **Carbon**: Present in saccharin.
- **Potassium**: Not present in saccharin.

5. **Conclusion**: The element that is not present in saccharin is **Phosphorus**.

### Final Answer:
**Phosphorus is not present in saccharin.**
