I see three options:
- if EmpId is defined in WORK.DEPARTMENT as numeric, then answer D is correct;
- if EmpId is defined in WORK.DEPARTMENT as numeric, then answer C is correct;
- if EmpId is not defined in WORK.DEPARTMENT, then also answer C is correct;
If data set WORK.DEPARTMENT has a numeric variable EmpId, which statement is true about the output dataset?
