Topic: Qualitative and Quantitative Data

We have to remember the definition of qualitative and quantitative data, qualitative data is used for describing the subject we want to explore, is focused on making exploratory approaches, meanwhile quantitative data is used to measure these characteristics giving it values.

So the only option that does not involve measures is b. Noting the color of a solution as it is heated, note that you can only tell the color like "blue", "red" etc etc. taking for example a. recording the temperature of a solid as it is warmed it involves measures as "35 °C", "37 °C" and so on.
