Question

Consider the event-controlled loop in the code fragment above and the eight counter-controlled loops beneath it. Which of these counter-controlled loops will perform precisely the same operations as the event-controlled loop? This question is internally recognized as variant 221.

Q.1

	fragment 1 contains the correct code
	fragment 2 contains the correct code
	fragment 3 contains the correct code
	fragment 4 contains the correct code
	fragment 5 contains the correct code
	fragment 6 contains the correct code
	fragment 7 contains the correct code
	fragment 8 contains the correct code
	none of the above

foo = 0
while (foo <= 840):
xyz (foo)
foo += 3
# code fragment 1 starts on the next line
for foo in range (841, 3):
xyz (foo)
# code fragment 2 starts on the next line
for foo in range (0, 841, 3):
xyz (foo)
# code fragment 3 starts on the next line
for foo in range (0, 841, 4):
xyz (foo)
# code fragment 4 starts on the next line
for foo in range (841, 4):
xyz (foo)
# code fragment 5 starts on the next line
for foo in range (840, 4):
xyz (foo)
# code fragment 6 starts on the next line
for foo in range (0, 840, 4):
xyz (foo)
# code fragment 7 starts on the next line
for foo in range (0, 840, 3):
xyz (foo)
# code fragment 8 starts on the next line
for foo in range (840, 3):
xyz (foo)
