Which of the following describes qualitative data?
taking the mass of an object using a balance.
measuring the volume of an object by water displacement.
recording the temperature of a solid as it is warmed.
noting cloudiness occurs when two solutions are mixed.

Option (d) is the correct answer.

Explanation:

A quantitative data is defined as the data which can only be described in numbers or figures.  

For example, mass of an object is 50 kg.

This is a quantitative data as mass is represented in figures.

On the other hand, a data which describes the nature of a substance and that can only be described in words as there will be no figures or numerical data then it is known as a qualitative data.

For example, Noting cloudiness occurs when two solutions are mixed is a qualitative data.

Thus, we can conclude that the statement noting cloudiness occurs when two solutions are mixed, describes qualitative data.
