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?

ukr =0 while (ukr +=7 \# code fragment 1 starts on the next line for ukr in range (0,771,7) : qux(ukr) \# code fragment 2 starts on the next line for ukr in range (0,770,8) : qux (ukr) \# code fragment 3 starts on the next line for ukr in range (0,771,8) : qux (ukr) \# code fragment 4 starts on the next line for ukr in range (771,8): qux (ukr) \# code fragment 5 starts on the next line for ukr in range (770,7): qux (ukr) \# code fragment 8 starts on the next line for ukr in range (770,8): qux (ukr) for ukr fer fragment 6 starts on the next line qux (ukr)
