C Correct answer
Explanation

In SAS DATA step logic, the assignment statements execute sequentially. When x=4, the condition 'if x=4' is true (using single = for comparison in SAS), so y='four'. The ELSE IF never executes. Later, x is reassigned to 7, but y remains 'four' - the IF/ELSE doesn't re-evaluate. Final values: x=7, y='four'.
