Assertion : Aspartame is used as artificial sweetener in cold drinks.
Reason : Aspartame is stable under cold conditions.

Answer

To analyze the assertion and reason provided in the question, we can break it down into the following steps:

### Step 1: Understanding the Assertion
The assertion states that "Aspartame is used as an artificial sweetener in cold drinks."
- Aspartame is indeed a widely used artificial sweetener, particularly in beverages. It is known for being much sweeter than regular sugar, which allows it to be used in smaller quantities.

### Step 2: Understanding the Reason
The reason states that "Aspartame is stable under cold conditions."
- While aspartame is stable at room temperature, it is important to note that it is not stable at high temperatures. This means that while it can be used in cold drinks, it should not be used in cooking or baking where high temperatures are involved.

### Step 3: Evaluating the Relationship
Now we need to evaluate whether the reason correctly explains the assertion.
- The assertion is true (aspartame is used in cold drinks), but the reason is misleading. Aspartame is not stable at high temperatures, which is why it is primarily used in cold beverages rather than in hot food or baking.

### Step 4: Conclusion
Based on the analysis:
- The assertion is true, but the reason is not accurate in the context of aspartame's stability. Therefore, while both statements are true, the reason does not correctly explain the assertion.

### Final Answer
The correct conclusion is that the assertion is true, but the reason is not a correct explanation of the assertion.
