yes, B, .. the if statement selects the two observations, which do not contribute fully to the merge (s. code below). data emp_name; infile datalines; input name $ empid; datalines; Jill 1864 Jack 2121 Joan 4698 John 5463 ; data emp_dept; infile datalines; input empid department $; datalines; 2121 Acc 3567 Fin 4698 Mar 5463 Acc ; data all; merge emp_name (in=emp_n) emp_dept (in=emp_d); by empid; if (emp_n and not emp_d) or (emp_d and not emp_n); run;

Yes. B is correct since there is 'or' between two conditions.

if not A and not B the answer is 2, otherwise, the answer should be 1.
