Hint: The process of arranging data into sequences according to their common characteristics is defined as Classification. To answer this particular problem, we should have basic knowledge of the different types of classifications and their definitions.

Complete step-by-step answer:
Under qualitative classification, data are classified on the basis of some attributes or qualities like honesty, beauty, intelligence, literacy, marital status etc. Example of a qualitative classification is population being divided on the basis of marital status as married or unmarried etc.
Similarly, when the data are classified according to geographical location or regions (like states, cities, zones, areas,etc) it is known to be a geographical classification and when data are observed over a period of time the type of classification is referred as chronological classification .
Therefore, it is quite clear that qualitative classification can only be found whether it is present or absent in the units of study.
Hence, Option A is the correct option.

Additional Information:
The different basis of Classification are:
(1) Geographical Classification: When data are classified with reference to geographical locations such as countries, states, cities, districts, etc. it is known to be Geographical Classification.
(2) Chronological Classification: When data are grouped according to time, such a classification is defined as a Chronological Classification.
(3) Qualitative Classification: This type of classification is made on the basis of some attributes or qualities like honesty, beauty, intelligence, literacy, marital status etc.
(4) Quantitative Classification: Under this classification, data are classified on the basis of some measurable characteristics like height, weight, age, income, marks of students, etc.

Note:The data type, in which the classification of objects is based on attributes (quality) is called as qualitative data whereas, the data type which can be counted and expressed in numbers and values is called quantitative data. The analysis is non-statistical when the data type is qualitative. Qualitative data is a type of data that describes information and is highly significant as qualitative data are categorical and unique to one individual.
