Which of the following is an example of quantitative data?

Quantitative data refers to information that can be quantified and expressed numerically. It involves measurements that allow for mathematical calculations and statistical analysis. The temperature of boiling water is a prime example of quantitative data, as it can be measured in degrees (Celsius or Fahrenheit) and provides a specific numeric value that indicates the thermal state of the water.

In contrast, the other examples present qualitative data. For instance, the colors of cars in a parking lot represent categorical distinctions without a numeric value. Feedback on a restaurant's service usually consists of opinions or descriptive statements that convey sentiments but lack numerical quantification. Similarly, descriptions of a sunset, while rich in visual detail, do not provide measurable data that can be categorized numerically. These distinctions highlight why the temperature of boiling water stands out as the correct answer in this context.
