A.
Errors at lines 7 and 8 cause compilation to fail.
B.
The program prints pairs of values for x and y that might not always be the same on the same line (for example, “x=2, y=1”).
C.
The program prints pairs of values for x and y that are always the same on the same line (for example, “x=1, y=1”. In addition, each value appears twice (for example, “x=1, y=1” followed by “x=1, y=1”).
D.
The program prints pairs of values for x and y that are always the same on the same line (for example, “x=1, y=1”. In addition, each value appears only for once (for example, “x=1, y=1” followed by “x=2, y=2”).
