Answer:
The correct option is B) Qualitative and discrete.
Step-by-step explanation:
Consider the provided information.
Quantitative variable is the variables that can be determined by counting or measuring something.
Qualitative variable is the variables that can't be determined by counting or measuring something.
If the value is obtained by counting then it is called discrete variable, If the value obtained by measuring then it is called continuous variable.
Since the relationship can't be measure by counting so it it qualitative variable.
We can calculate the regular contact days so it is discrete variable.
Therefore, the correct option is B) Qualitative and discrete.
