To determine which situation does NOT yield variability, we need to analyze each option:

1. **I. How many grams of sugar are in a 12-ounce can of Dr. Pepper?**
   - This is a specific measurement for a single product. The amount of sugar in a 12-ounce can of Dr. Pepper is fixed and does not vary.

2. **II. How much sugar is used to make a gallon of punch?**
   - This can vary depending on the recipe or personal preference. Different recipes may call for different amounts of sugar, so this situation does yield variability.

3. **III. How many grams of sugar does a teenager consume each day?**
   - This can vary significantly from one teenager to another based on their diet, activity level, and personal choices. Therefore, this situation also yields variability.

4. **IV. How much sugar is in an 8-ounce glass?**
   - Similar to the first situation, if this refers to a specific drink (like a soda), the amount of sugar is fixed for that specific drink. However, if it refers to different drinks, it could vary. Assuming it refers to a specific drink, it does not yield variability.

Now, let's summarize the findings:
- Situation I does not yield variability.
- Situation II does yield variability.
- Situation III does yield variability.
- Situation IV does not yield variability if it refers to a specific drink.

Based on this analysis, the situations that do NOT yield variability are I and IV.

Thus, the correct answer is:
**(D) I and IV only**.
The answer is (D) I and IV only.
