A 4 bit ripple counter and a 4 bit synchronous counter are made using flip-flops having a propagation delay of 10 ns each. If the worst case delay in the ripple counter and the synchronous counter be R and S respectively, then

R = 10ns, S = 40ns

R = 40ns, S = 10ns

R = 10ns, S = 30ns

R = 30ns, S = 10ns
