Answer: 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.
