A ripple counter is made with three positive edge triggered flip-flops. If the output of previous lower significant bit flipflop is used as a triggering clock pulse of the next higher significant bit flip-flop, then the resultant counter is a
A MOD 3 up counter
B MOD 3 down counter
C MOD 8 bit up counter
D MOD 8 down counter
since all are positive edge triggered flip flops ,so shouldn't the answer be mod 8 up counter??
