A. Identifier
B. Categorical
C. Quantitative
D. Qualitative
The answer to this question is C. Quantitative
Explanation:

Moreover, this is the opposite of qualitative variables that involve using qualities.

Also, other types of variables such as qualitative or categorical are not involved because these are related to qualities rather than numbers.
