Answer

To determine which of the given options is an artificial sweetening agent, we can analyze the three compounds mentioned in the video transcript: Saccharin, Elydame, and Aspartame.

### Step-by-Step Solution:

1. **Identify the Compounds**:
The compounds mentioned are Saccharin, Elydame, and Aspartame.

2. **Analyze Saccharin**:
- Structure: Saccharin has a structure that includes a benzene ring and is known for its sweetness.
- Properties: It is approximately 300 to 400 times sweeter than sucrose and is commonly used in drinks, candies, and cookies.
- Conclusion: Saccharin is an artificial sweetener.

3. **Analyze Elydame**:
- Structure: Elydame is described as having a four-membered ring with various functional groups.
- Properties: It is an aspartic acid-containing dipeptide sweetener and is used in drinks, cold drinks, and wine. Its half-life under hot or acidic conditions is twice that of aspartame.
- Conclusion: Elydame is also an artificial sweetener.

4. **Analyze Aspartame**:
- Structure: Aspartame contains various functional groups including NH2, double bond O, and a benzene ring.
- Properties: It is about 200 times sweeter than sucrose and is commonly used in food and beverages.
- Conclusion: Aspartame is an artificial sweetener.

5. **Final Conclusion**:
Since all three compounds (Saccharin, Elydame, and Aspartame) are identified as artificial sweeteners, the answer to the question "Which of these is an artificial sweetening agent?" is that all of them are artificial sweeteners. Therefore, the answer is **D. All of these**.
