A student was comparing the solubility of equal amounts of table salt and table sugar at different temperatures. The table below shows the four samples used and the temperature of the water they were dissolved in.

| Sample | Name | Chemical formula | Temperature (°C) |
|--------|--------------|---------------------|------------------|
| 1 | Table sugar | C₁₂H₂₂O₁₁ | 80 |
| 2 | Table sugar | C₁₂H₂₂O₁₁ | 45 |
| 3 | Table salt | NaCl | 55 |
| 4 | Table salt | NaCl | 63 |

Which of the samples most likely had the highest solubility?

A. 1
B. 2
C. 3
D. 4

Based on the data provided in the table, the solubility of a substance generally increases with an increase in the temperature of the solvent. Here, we have four samples dissolved in water at different temperatures.

Here are the temperatures for each sample:
1. Sample 1: 80°C
2. Sample 2: 45°C
3. Sample 3: 55°C
4. Sample 4: 63°C

To determine which sample most likely had the highest solubility, we look for the sample with the highest temperature because higher temperatures usually indicate higher solubility.

Comparing the temperatures:
- Sample 1: 80°C
- Sample 2: 45°C
- Sample 3: 55°C
- Sample 4: 63°C

The highest temperature is 80°C, which corresponds to Sample 1.

Therefore, the sample that most likely had the highest solubility is:
1.
