Make a truth table. Look at what state the flip flops are in with a count of 9. Then what happens with the next clock?

we are doing this as well, I can follow through how the last flip-flop is going to be reset, but the others. Any help please? I understand that with B and C both low going through an AND gate J is forced low and last flip flop is reset, how are the first three reset?
