Final Answer :
C
Explanation :
The classification of student class designation is an example of an ordinal random variable, as there is a clear order and ranking among the categories (freshman being the lowest and senior being the highest). It is not a nominal variable because there is an inherent order to the categories, and it is not an interval variable because the numerical differences between the categories do not have any meaningful interpretation. It is also not a parameter, which is a numerical value describing a population parameter, whereas student class designation is a variable describing individual students.
