&nbsp;&nbsp;&nbsp;&nbsp;  CharEmpid=EmpId;<br>
  run;<br>
<br>
If data set WORK.DEPARTMENT has a numeric variable EmpId,which statement is true about the output dataset?</font></p>
<p><font size="4" face="宋体">&nbsp;&nbsp;&nbsp;&nbsp;  A. The type of the variable CharEmpid is numeric.<br>
&nbsp;&nbsp;&nbsp;&nbsp;  B. The type of the variable CharEmpid is unknown.<br>
&nbsp;&nbsp;&nbsp;&nbsp;  C. The type of the variable CharEmpid is character.<br>
